We all love a good brain teaser, especially when it involves math—whether we admit it or not. A tricky math problem recently went viral, leaving the internet divided and proving once again that even simple-looking equations can be deceptive.
My Math Struggles & A Challenge
Here’s a quick personal anecdote: I recently started preparing for the GRE and realized that I hadn’t taken a formal math class in nearly nine years. Confidence? Gone. My quantitative reasoning skills? Rusty at best. So, I decided to brush up by taking online high school math courses, starting from the absolute basics.
When I came across this viral math puzzle that was stumping the internet, I thought, “This is my moment! Let’s see if I still have my 9th-grade math chops!” Spoiler: I did not.

The Viral Math Puzzle Taking the Internet by Storm
The problem originally surfaced in Japan, where researchers found that only 60% of people in their 20s managed to solve it correctly. It quickly spread online, turning into yet another viral challenge because, apparently, we love testing our brains with tricky equations (or we just enjoy arguing over the answers).
At first glance, the problem looks simple. But the devil is in the details. My gut told me there was some sort of trick involved—it seemed too easy. However, instead of embarrassing myself by attempting it publicly, I turned to the internet for guidance. If there’s one thing I’ve learned, it’s that someone, somewhere, has already tackled your problem and made an instructional video about it. So, I spent my morning watching people do math on YouTube. Exciting stuff.
The Math Problem:
6 ÷ 2(1 + 2) = ?
Go ahead, solve it. I’ll wait.

Common Wrong Answers
If you got 1 or 9, you’re not alone. Many people arrived at these answers because of a little acronym called PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction).
You may remember PEMDAS from school—or perhaps the mnemonic “Please Excuse My Dear Aunt Sally.” The rule dictates that you must solve problems in this specific order:
- Parentheses
- Exponents
- Multiplication & Division (from left to right)
- Addition & Subtraction (from left to right)
So, following PEMDAS, some people calculated it as:
- Solve inside the parentheses: (1 + 2) = 3
- Rewrite the problem: 6 ÷ 2(3)
- Some then treated 2(3) as a single term and multiplied first: 6 ÷ 6 = 1
However, others applied division before multiplication:
- 6 ÷ 2 = 3
- Then, 3 × 3 = 9
Both groups were confident in their logic, but only one approach was correct.
The Correct Answer
The correct answer is 9. Here’s why:
Step 1: Solve the Parentheses First
(1 + 2) = 3
Now the equation is rewritten as:
6 ÷ 2(3)
Step 2: Follow the Order of Operations
According to PEMDAS, division and multiplication are performed from left to right (since they share the same level of priority in the hierarchy).
- 6 ÷ 2 = 3
- 3 × 3 = 9
Wait… Isn’t the Answer 1?
Some people argue that implicit multiplication (like 2(3)) takes precedence over division. However, modern mathematical notation treats multiplication and division equally. Since they appear side by side in the equation, we solve left to right.
If the equation had been written as:
6 ÷ (2 × 3)
Then, you would multiply first and get:
6 ÷ 6 = 1
But because the given equation lacks parentheses around 2(3), the correct answer remains 9.
Why People Get It Wrong
The confusion stems from different ways of interpreting notation and how we were taught order of operations. In some older textbooks, implicit multiplication (like 2(3)) was given higher priority than division, leading to the alternative answer of 1. However, under modern mathematical conventions, division and multiplication hold equal weight and should be solved left to right.

Math Rules Are Not Always Universal
Believe it or not, different countries and academic institutions teach math slightly differently. Some older math textbooks might suggest treating multiplication next to parentheses as having higher priority, while others follow the standard left-to-right rule. This is why debates like this never really die down—people were simply taught different methods!
How to Avoid Future Math Confusion
- Always follow the standard order of operations – PEMDAS (or BODMAS, if you learned it that way).
- If in doubt, add brackets – Parentheses make everything clearer and help prevent confusion.
- Be consistent – If you’re solving problems with others, use the same approach so that everyone gets the same answer.
- Check multiple sources – Sometimes, even textbooks disagree. Looking at different explanations can help clarify tricky concepts.
Final Thoughts
This viral math problem is a perfect example of how simple-looking equations can spark endless debate. The way you approach it depends on how you learned math, but if you apply PEMDAS correctly, the answer is 9—at least according to current conventions.
So, did you get it right, or are you questioning everything you thought you knew about math? Either way, at least we can all agree that math is a lot trickier than it looks!
I Overheard My Neighbor’s Daughter and My Husband Discussing Their Affair – Instead of Making a Scene, I Invited Her to Our House the Next Day

When Lexie overhears her husband and the neighbor’s daughter discussing their affair, she doesn’t cry or confront them. Instead, she plans. With a clever invitation and a jaw-dropping twist, she flips the script on their betrayal, serving up karma with a side of sass. Revenge has never been this satisfying.
My husband, Mark, and I had been married for ten years. Two kids, a mortgage, and what I thought was a solid life bound us together. Sure, Mark wasn’t much help around the house.
He didn’t cook, clean, or manage the endless chaos of raising kids.

That was all me.
Exhausting?
Absolutely.
But I told myself it was fine because “we’re a team, Lexie.”
Except, apparently, Mark had decided to join a different team altogether.
It started with a bag of groceries.

I had just pulled into the driveway after a grueling trip to the store. My car was packed with heavy bags and I was mentally preparing for the solo effort of hauling everything inside.
Mark, as usual, wouldn’t lift a finger.
That’s when I heard voices coming from the porch.

It was Mark, chatting with Emma, our neighbor’s 25-year-old daughter who’d recently moved back to town. Her parents were so proud when she got into her internship after she studied interior design.
Now, she and Mark stood there laughing like old friends.
I almost called out to say hello, but something made me stop.
I ducked behind my car, hidden by the shadows and groceries, and listened.

“I can’t believe she hasn’t figured it out yet,” Emma said, her laughter ringing through the cool afternoon air.
Mark chuckled in response.
“She’s so busy with the kids and the house, Em. Lexie barely notices anything else. She’s gotten so gray, too. But she just brushes her hair the other way to cover it up. Honestly, she’s let herself go so much. She doesn’t even look like a woman to me anymore. She’s nothing compared to you, my princess.”
Emma giggled.

“Well, lucky for you, mister, I’m here now. You can parade me all your want. And trust me, there’s no gray hair in sight.”
Then they kissed.
Kissed?!
I clutched a bag so tightly that I could feel the plastic starting to tear. My vision blurred with tears, the humiliation and rage coursing through me. They continued their conversation, the shameless flirting, all oblivious to my presence.

But other than those few tears, I didn’t cry properly. I didn’t scream or shout. I didn’t confront them.
Instead, I quietly carried the groceries inside, using the back door, and started my planning.
The next morning, I woke up with a calmness that surprised even me. I made Mark breakfast, his eggs fluffy and the bacon extra crispy. I made his coffee with a dash of cinnamon, just the way he liked it. I kissed him goodbye and waved cheerfully as he left for work.

Once he was gone, I walked next door and knocked on Emma’s door.
She opened it, visibly surprised.
“Oh! Hi, Mrs…Um, hi, Lexie,” she stammered, her smile overly bright.
“Hi, Emma,” I said warmly. “I was wondering if you could come over tomorrow evening. I could really use your advice on something.”

She blinked, her smile faltering.
“Advice? On what?”
“Well,” I hesitated, letting my voice sound unsure. “I’ve been thinking about redecorating the living room. Your parents mentioned you studied design, and I thought you could help pick out colors or furniture ideas. It’ll just take a little while.”

For a moment, doubt flickered in her eyes. Then she tilted her head, a sly smile forming.
“Oh, I’d love to help! What time?”
“I think seven will be fine? Dinner time!” I said, my own smile sweet and sincere. “Thanks so much, Emma. You’re a lifesaver.”
Emma showed up the next evening, dressed to impress. She greeted me with her usual cheerful demeanor, practically radiating confidence.

I welcomed her warmly and led her inside.
“Oh, before we get to the living room,” I said casually. “I wanted to show you a few things.”
I guided her though the house, pointing out key areas of domestic responsibility.
“Here’s the dishwasher. You’ll need to load it every night because Mark doesn’t bother, of course. The kids’ laundry goes here, but please, be sure to separate the loads, since they’re sensitive to different detergents.”

She just stared at me.
“Oh, and here’s the schedule for their after-school activities. You’ll need to pick them up on Tuesdays and Thursdays, but Wednesdays are free for errands. I’ve written down the plumber, electrician, and pediatrician’s numbers. Just in case.”
Emma’s smile faltered, her face growing pale.
“And this,” I said, leading her into the kitchen, where the smell of a roast chicken filled the room.

“This is where you’ll prep all the meals. And let me tell you, other than the breakfasts, and different school and work lunches, there are snacks and desserts and it’s all just a lot. Mark likes his steak medium-rare, by the way. The kids will only eat steak if it’s cooked all the way through. The deader the better.”
She gasped.
“Don’t expect Mark to say thank you, manners are not his thing. The kids are picky eaters, I’m sorry to say, but you’ll figure it out.”

She stared at me, wide-eyed.
“Uh, Lexie. I’m not sure… I don’t think… I didn’t offer to babysit them.”
Just then, Mark walked in. His face went pale the moment he saw us.
“Lex, what’s going on?” he asked, his voice tight and high-pitched.

“Oh,” I said brightly. “I probably should have included you in this, too. But I’m just showing Emma how to run the house. Since you think I’ve let myself go, I figured that it’s time for me to prioritize myself. And also, maybe it’s time for me to find someone who sees me as his princess. Emma, you’ll be taking over everything I do. Good luck!”
Before either of them could respond, there was a knock on the door.
I opened it to reveal Emma’s parents. The same couple who often babysat my kids if I was in a bind.

“Oh! It smells delicious! I told Annie that you were going to make your roast chicken, Lexie,” Emma’s father said, joyfully.
“Thanks for coming, Anne and Howard. And thank you for raising such a helpful daughter,” I said. “She and Mark have grown so close that I thought it was time to make her part of the family.”
“Wait, what?” Anne asked, her eyebrows furrowed.

“I’m leaving and Emma’s going to take care of everything now! You must be so proud of your little girl.”
Emma’s mom looked confused. Her dad, on the other hand, livid.
“Emma,” her mom said. “Tell me that this isn’t true. Tell me that this isn’t what I think it is.”
“It’s not what it looks like!” Emma stammered.

Mark, ever the coward, tried to shift the blame.
“Lexie, this isn’t fair! Emma came to me! She came onto me!”
“Oh, did she?” I asked, raising an eyebrow. “So, you’re saying that you’re not responsible for sneaking around with a 25-year-old while insulting your wife?”
He opened his mouth to argue, but Howard cut him off.
“Mark, this is on you. Emma, this is equally on you. Let’s leave. Now.”

Emma shot me a venomous glare before storming out. Her parents followed, muttering a thousand apologies as they went.
Mark turned to me, desperation etched across his face.
“Lexie, please, babe,” he said. “Let’s talk about this. We’ve been together for so long… you owe me a conversation, at least.”
“Oh, sweetie,” I said. “We’ll talk, don’t you worry. My lawyer will call you tomorrow. But for now, I think you should pack your bags and leave.”

“Where will I go?” he asked pathetically. “My family lives in a different state.”
“I don’t really care, Mark,” I said, taking the chicken out of the oven. “Go to a motel. Go to a friend. Join the circus.”
“And the kids? Where are the kids?”
“They’re with my sister. And they’ll stay there until you sort your nonsense out. You can tell them the truth after the lawyers work out a settlement. I’m not going down without a fight, Mark.”

A week later, I heard through the grapevine that Emma had dumped Mark.
“It was fun while it lasted, but I didn’t sign up to play mom. To him or his kids.”
Two weeks later, Mark came back.
“What do you want?” I asked, seeing the bunch of flowers in his hand.

“I’ve been so miserable without you,” he said, practically begging. “Please, let me come back. Please, Lexie. We can fix this. I miss my kids. I miss our family.”
“I don’t care, Mark!” I blurted out. “I truly don’t care. Now, if you don’t have anything productive to do here, then leave. The kids are at a playdate, and I’m only fetching them in a few hours.”
Then, I closed the door, leaving him speechless.

It’s been months since that night, and I’ve never been happier. I’ve rediscovered pieces of myself I thought were long gone. I’ve started taking up salsa dancing, and with that, my confidence, joy and freedom came flooding in.
Amid the chaos, my kids and I have found a new rhythm, one filled with laughter and love.
As for Mark? He’s still single. And from what I hear, Emma’s parents aren’t thrilled with her either. But Anne does bake cakes and pies and sends them over often. And Howard likes to rake up the leaves in our front yard.
Karma’s a funny thing, isn’t it?
