Math professor shows how adding and subtracting left to right is actually easier and faster

Mind. Blown.

Howie Hua shares helpful math tips and tricks on social media.

Math is weird.

On the one hand, it's consistent—the solutions to basic math problems are the same in every country in the world. On the other hand, there are multiple strategies to get to those solutions, and it seems like people are still coming up with new ones (much to the chagrin of parents whose kids need help with homework using methods they've never learned).

Math professor Howie Hua shares math strategies that make math easier on social media, and his videos are fascinating. Hua, who teaches math to future elementary school teachers at Fresno State, demonstrates all kinds of mental math tricks that feel like magic when you try them.

For instance, Hua has two videos showing how easy and quick it is to add multidigit numbers left to right instead of right to left, and it's genuinely mind-blowing.


Check out how he explains why adding left to right is "underrated."

OK, seriously. That is way easier to do in your head. It's basically putting the numbers into expanded form and adding them, which makes it easier to visualize.

Adding this way makes sense, but subtracting is a bit more complicated, right?

Wrong, apparently. Watch Hua work his math sorcery subtracting two and three-digit numbers.

@howie_hua

Did you know you can subtract left to right? #math #mathematics #mathtok #maths #teachersoftiktok #teacher #mathtricks #mathtrick

Holy moly. That's faster than the right-to-left, borrow-from-the-next-column method, isn't it? And again, so much easier to visualize what's actually happening, though I don't know if I could fully do this in my head like I could with the left-to-right addition.

Hua recently shared another cool subtraction trick for problems with minuends that have a lot of zeroes. (The minuend is the first number in a subtraction problem. Don't be too impressed. I had to look it up.)

Check this out:

@howie_hua

An underrated subtraction strategy #math #mathematics #mathtok #maths #teachersoftiktok #teacher #mathtricks #mathtrick

So simple, so time-saving and so something I would never have figured out on my own.

These tips and tricks might come in handy for anyone, but they're especially useful for kids who are having to do these kinds of math problems at school all the time. Even if they're supposed to solve the problem with a different strategy, these methods can be a quick way to check their answers.

Anything that makes math easier, I say. You can watch Hua's videos on TikTok, YouTube and Twitter.

Fed up parents explain why they 'never want to bring the kids over' to visit

Can't you guys come to us for once?

It's a good news/bad news situation for parents of young kids.

The good news? Everyone wants to spend time with the kids! Grandparents, aunts and uncles, friends. They all want a relationship and lots of special moments with the little ones.

The bad news? One phrase:

"When are you bringing them over?"

Parents have been frustrated by the expectations of orchestrating stressful visits for generations — loading the kids in a car or on an airplane only to spend hours chasing them around in an un-baby-proofed environment and watching routines go to hell.

Now they're sounding off on social media and airing their grievances.

Why visiting grandparents and other relatives is so challenging for parents

A mom recently took to Reddit to vent about everyone in her life wanting her to "bring the kids to them."

"My parents live 30 mins away and always bug me about not coming to visit them," she writes. They constantly ask, "Why don't you bring our granddaughter to come see us?"

The fascinating discussion highlights a few things that make arranging visits with young kids a potential nightmare for parents.

Grandparents' houses are rarely childproofed

Grandparents love their breakable decor! Ceramic doo-dads, glass vases everywhere. They can't get enough. And while they should be able to decorate their house however they see fit (they've earned the right!) that doesn't make it a good environment for toddlers and babies.

"Last week was the last straw, I took my daughter to my parents and of course she went EVERYWHERE! flooded their toilet, broke a vase, and tried multiple times to climb their furniture," the Reddit mom writes.

Parents in a foreign environment are on constant safety duty and can rarely sit down

Let's be honest. Sometimes these "visits" are hardly worth the effort. After all, it's hard to get much catch up time when you're dutifully chasing your kid around.

"They don’t understand that my 3 yo ... is absolutely wild," writes another user in the thread. "She has no self preservation and nothing we do works. She doesn’t listen, she throws, she bites, she refuses to use the potty. It’s exhausting and then ... they expect us to entertain them, when I’m trying to just keep my kid from jumping off the stairs and into an ER visit."

Even just putting the kids in the car for a 20-minute drive is more work than it seems

Taking the kids out of the house requires packing a bag, bringing extra clothes, loading up on snacks, etc.

It seems easy to "pop over" but it actually absorbs the majority of the day between prep, visit, and aftermath.

Naps and routines go to hell

Parents with babies and toddlers know all too well — there is a price to pay for taking the kids out of the house for too long.

Chances are, the baby won't nap in a strange environment and then you're stuck with a cranky kid the rest of the night.

Kids with special needs require even more consistency

Kids with autism or ADHD can really struggle outside of their zone of safety. They might become severely dysregulated, have meltdowns, or engage in dangerous behaviors.

Explaining and mediating the generational divide

Why is this a conflict almost all parents can relate to?

Is this a Boomer vs Millennials thing?

Some experts think that generational values and traditions might play a role.

"Many Boomers were accustomed to more traditional, hierarchical family dynamics, where visiting grandparents was a way for the younger generation to show respect," says Caitlin Slavens, a family psychologist.

But that's not to say this is a new problem. I can remember my own parents driving me and my brothers over an hour to visit my grandparents seemingly every other weekend, but very few occasions where they came to visit us. It must have driven my parents nuts back then!

Plus, it's easy to forget that it's hard for older people to travel, too. They may have their own issues and discomforts when it comes to being away from their home.

"But for today’s parents, balancing careers, kids’ routines, and the demands of modern parenting is a much bigger undertaking. Grandparents might not always see how childproofing their space or making the trip themselves could make a huge difference, especially considering how travel and disruption can impact younger kids' moods and routines," Slavens says.

"So yes, this divide often comes down to different expectations and life experiences, with older generations potentially not seeing the daily demands modern families face."

Is there any hope for parents and grandparents coming to a better understanding, or a compromise?

"First, open conversations help bridge the divide—explain how much of a difference it makes when the kids stay in a familiar space, especially when they’re very young," suggests Slavens.

"Share practical details about the challenges, like childproofing concerns or travel expenses, to help grandparents see it from a parent’s perspective. You might even work together to figure out solutions, like making adjustments to create a more child-friendly space in their home or agreeing on a shared travel plan."

Ultimately, it's a good thing when grandparents, friends, and other relatives want to see the kids.

We all have the same goal.

"It’s helpful to approach the topic with empathy, focusing on everyone’s goal: more quality time together that’s enjoyable and low-stress for everyone involved. For parents, it’s about setting boundaries that work, and for grandparents, it’s about recognizing that flexibility can really show the parents that you are ... willing to make adjustments for their children and grandchildren."

Enjoyable, low-stress quality time — that's something everyone can get behind.

A small boat made by middle schoolers sailed across the ocean all the way to Norway

This is pretty much the coolest school project ever.

Facebook

The Rye Riptide washed up on the shores of Norway.

This story brings a whole new meaning to the word friendship.

In October 2020, the middle schoolers of Rye Junior High, in Rye, New Hampshire, bid a bon voyage to their handmade mini-boat, which set sail off the coast of New Hampshire to who-knows-where.

Measuring only 5.5 feet, the “Rye Riptides” was indeed a small ship. It ran crewless, but carried a bountiful cargo of colorful artwork made by students, along with a GPS tracking device that reported the boat’s location … sometimes.

Cut to 462 days and 8,300 miles later, and what started out as a simple science project became a surprise discovery for some Norwegian sixth graders, and a fun new connection across the Atlantic.

Rye Junior High had partnered with Educational Passages, a nonprofit organization that aims to connect students around the world to the ocean and each other. Once the kit arrived, the kids started building while learning about ocean currents, science and math. However, science teacher Sheila Adams shares that the more artistic, right-brained activities equally found their way into the curriculum. “The students needed to use their writing skills to inform others about their mini-boat project, describe our school and town to people of other languages, just in case, and write requests to get the boat deployed,” she said in a release.

…not me feeling jealous of some middle schoolers right now…

COVID-19 nearly threatened to knock the Rye Riptides off its course. The boat had been constructed, but not yet decorated, when students were moved to taking class online. Then, there was the matter of launching the boat. Which Cassie Stymiest, director of Educational Passages, noted was “challenging with all the restrictions in place.” Luckily, creativity, resourcefulness and a little technology saved the day. Working remotely, each piece of art was done at home, then scanned, printed and made into a collage. Then, Ms. Stymiest connected with the Sea Education Association (SEA), which set the Rye Riptides on its journey.

Seriously, my inner child is geeking out with this stuff.

Would the boat make it to Europe? Rye student Solstice Reed wasn’t so sure. “Honestly, I thought it would sink,” she admitted to the Portsmouth Herald. Considering the boat was cruising the ocean waters during hurricane season, the skepticism was well-founded. During the more tumultuous periods, the GPS signal only came in intermittently. And for a long while, there was nothing but radio silence.

But then, at long last, on the small Norwegian island of Smøla, the Rye Riptides successfully made it to dry land. Sure, it was a bit dismantled and covered in barnacles, but inside, all the adorable trinkets remained intact. The Smøla students peered with wonder into their bounty of photos, signed facemasks, fall leaves, acorns and state quarters, gifts sent out almost two years ago.

The voyage of the small boat has gone viral in a big way, sailing across social media, and making headlines. And now, Educational Passages plans on facilitating video meet-ups between Rye Junior High and the school in Norway, “to continue building this new relationship to learn from each other and about the shared Atlantic Ocean between them.” Plus, NPR reports, the students of Smøla would be writing a letter to their new American friends.

Human connection found its way across the sea in the most wholesome and magical way. It’s really cool to see that educational programs like this exist, impacting both the hearts and minds of young students. Mission, successful.

A seemingly simple Final Jeopardy question stumped all three contestants in 1984

It was only Alex Trebek's second day on the job when all three contestants gave the same wrong answer and all ended up with $0 .

Representative photo by Rosemaryetoufee

"Jeopardy!" is one of the most popular trivia shows in the world.

The popular game show "Jeopardy!" originated in 1964, and for six decades it has stumped contestants and viewers with tough trivia questions and answers (or answers and questions, to be more accurate). Competing on "Jeopardy!" is practically synonymous with being a smartypants, and champions win lifelong bragging rights along with whatever monetary winnings they end up taking home.

To win "Jeopardy!," you place a wager in the Final Jeopardy round with whatever money you've collected through the first two rounds. All three contestants write down their wagers based solely on the category given, then they have 30 seconds to write down the question for the same answer after it's revealed. Very rarely do all three contestants get the Final Jeopardy wrong.

But in 1984, on Alex Trebek's second day hosting the show, a deceptively simple Final Jeopardy answer answer resulted in all three contestants making the same wrong guess and ending the round with $0 each.

The category was "The Calendar," and after the contestants placed their bets, the answer was revealed: "Calendar date with which the 20th century began."

- YouTubewww.youtube.com

The 20th century was the 1900s, as most of us are aware, and all three contestants wrote down identical responses: "What is January 1, 1900?" But they were all incorrect. And unfortunately, all three had wagered their entire amount, leaving them with nothing across the board.

"Oh, I don't believe it!" exclaimed one of the contestants as they all laughed at the absurdity. "I'm at a loss for words," said Trebek.

A member of the audience asked what the correct answer–or question— was, and Trebek shared that the correct response would have been "What is January 1, 1901?"

If that seems confusing, it's probably because we all made a huge deal about the year 2000, marking it as the end of the 21st century as well as the turn of the millennium. But basically, we were wrong. Some people did point it out at the time, but the excitement and momentum of celebrating Y2K had us all in a frenzy and no one was going to wait until January 1, 2001 to celebrate the new millennium.

Why should we have? It all comes down to the fact that in the Gregorian calendar the first year wasn't 0 A.D., it was 1 A.D. The first century spanned from 1 to 100 A.D., the second century from 101 to 200 A.D. and so on, leading up to the 20th century officially being from 1901 to 2000. So January 1, 1901 is actually the date that the 20th century began, despite how unituitive it feels.

To be fair, you'd think a "Jeopardy!" contestant might recognize that the question seemed awfully simple for a Final Jeopardy round, but only having 30 seconds to think under pressure is tough. And it's not like these people lived in the internet era where random trivia questions like this regularly go viral, making us more aware of them. And this episode aired over a decade before the "Seinfeld" episode where Jerry explains the "no year zero" thing to Newman, who had planned a millennium party.

- YouTubeyoutu.be

As one person pointed out, the calendar answer is technically correct, but it's not the way the average person thinks of centuries, just as a tomato is technically fruit but the average person thinks of it (and uses it) as a vegetable. Even though there were some sticklers about the year 2000, most of us just went along with seeing it as the turn of the millennium because it felt like that's how it should be. It's kind of wild how most of us can think of something incorrectly but we just sort of collectively accept our wrongness about it.

The 1984 episode has been making the viral rounds, prompting people to share how much they miss Alex Trebek. The beloved, long-time "Jeopardy!" host died in 2020 at age 80 after a 20-month battle with pancreatic cancer. He worked up until the point where he couldn't anymore, even while undergoing chemotherapy. His final episode included a touching tribute honoring his 37 seasons with the game show, the end of an illustrious and iconic era.

Mom admits she isn't perfect in a hilarious 'back-to-school’ sign she made for herself

She was done before the first day even started.

First day of school can be exhausting … but for who?

It’s back-to-school time and that means new school supplies, a trip to Target for clothes and social media channels flooded with photos of kids holding chalkboards. Over the past decade, back-to-school photos with kids standing on their doorsteps with signs with their name, grade, year and teacher have been ubiquitous on social media.

There’s nothing wrong with the photos, they’re a cute way for parents and kids to mark the passage of time. For most parents, it’s a way to remember that it all goes by way too fast.

However, for the “perfect” parents out there who like to flaunt their Instagrammable lifestyle, they’re another way to show off their “flawless” first days on social media.

In an attempt to show parents they don't have to fall for the myth of perfection on social media, Jeni Bukolt—a mother of two boys age 8 and 12 from Waxhaw, North Carolina—posted a first-day photo of herself looking burnt out and wearing sunglasses. School hadn’t even begun yet.

"Mom's first day of school,” the handmade sign read. "I am 42 years tired. I'll probably miss a school 'theme' day. I really like sleep. Please don't ask me to volunteer. But I will buy you supplies."

"I make signs for my kids each year but lately I've thought about how I always feel behind, as though I'm failing (in some way)," Bukolt told Today. Clearly, other parents feel the same because it was a hit with a lot of them on Instagram.

A lot of comments were from parents who thought the photo was a breath of fresh air during a stressful time of year. "Brilliant, you speak for millions!" cathycole wrote. "May we all survive the drop off/pick up lane," merakifitnessandpole added.

"I thought maybe if I can create a lighthearted moment, some other moms will laugh and understand we're all in this kind of struggle together. Like, let's have empathy for each other," Bukolt told Good Morning America.

Bukolt hopes her post builds an “empathy bridge” between parents. She’d also like to shine a little reality on the parents who feel judged on social media.

"I also feel like when you look at social media, there's all these, [picture perfect] worlds,” she added. “It's not the true story. And some people think like, 'Oh, they have it better or they're perfect,' and this is an opportunity to say no, we're all real human beings ... we're all in the struggle together."

But of course, there were some humorless parents who thought her post wasn’t supportive of teachers or her two sons. So Bukolt made a follow-up where she explained that she was just having fun.

“For the keyboard warriors… yes I do have a job, yes I love my kids and no, I don’t hate teachers. Back to work. Have a great day!” she wrote.

Parenting is hard and we all fall short of glory at times. Kudos to Bukolt for making us feel a little less alone and letting us know that some folks have already accepted their imperfections on the first day.

"If other moms can get a good laugh about it, then that makes my heart happy," she said.

Woman discovers her tireless dog has secretly been playing fetch with the neighbors

Bounder is living the good life.

Bounder playing fetch with his neighbor.

Every dog is different when it comes to playing fetch. Some have zero interest in playing, while others are obsessed with the game and won’t stop playing until their human friends force them to stop.

There are a lot of reasons why dogs love to play fetch. First, most dogs are genetically predisposed to chasing after objects that move, whether it’s a car or a squirrel. They also instinctually bring back prey to their dens.

“After a hunt, sometimes the wolf will carry the prey back to the den to be consumed safely with the pack, essentially ‘retrieving’ dinner for the family,” Katelyn Schutz, Certified Professional Dog Trainer of Wisconsin Pet Care, said according to BarkPost. “The game of fetch in our pet dogs is suggested to be a simple variation of this ‘prey-carrying’ behavior.”

Fetch also stimulates the reward centers in a dog’s brain, so once they get started playing they don’t want to stop. Bounder, Brittney Reynolds’ black Labrador, can’t get enough of catching and retrieving a tennis ball.

“He’s obsessed,” Reynolds told The Dodo. “He will play fetch until I make him stop.”


@brittneygoes

He brings it back to the edge of the fence. #blacklab #doglover #SeeHerGreatness

Bounders' obsession with the game led him to ask Reynolds’ neighbor to play fetch with him when she wouldn’t. She discovered the game had been going on in secret one day when she went outside to see why Bounder was barking and discovered he was asking the neighbor to play with him.

“The neighbor was sitting on his back patio with the ball gun on the table, and Bounder was staring him down and barking at him wanting to play,” Reynolds said. “I tried to tell him to stop barking, but the neighbor got up and started shooting the ball gun for him. It was just so cute. I went and thanked him for playing with my boy and found out that they had been doing this for a while.”

The neighbors had a ball gun to play fetch with their dog, Layla.

Reynolds shared a wholesome video of Bounder and the neighbor playing together and it went viral receiving over 6.8 million views. “Just found out my neighbor and my dog have been playing fetch together over the fence,” she captioned the video.

Some commenters thought the game was great for the dog and the neighbor, too. "I just watched all your videos on this and I'm in love with this story! Your dogs have new grandparents and they have a reason to stay active," Monica wrote.

"I hope that you know that allowing this is making that man’s day. You are a great neighbor and humanitarian. Thank you," another user wrote.

@brittneygoes

Caught the neighbor playing with a Bounder again. He looks forward to this. #goodneighbors #doglovers #Totinos425

“I am a huge dog lover, and it always makes me happy to see others treating dogs so well,” Reynolds said about her neighbor.

“Our dogs are our family, and I think you can tell a lot about a person by the way they treat animals.” Reynolds shared a follow-up video that showed the over-the-fence fetch game is still happening.
