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!
Our Stepdad Gifted My Mom a Pack of Toilet Paper for Her Birthday — Our Revenge on Him Was Harsh
My stepdad always made a big deal about being the “man of the house,” but when his “special gift” for my mom’s birthday turned out to be a pack of toilet paper, I decided it was time for payback. And let’s just say someone else ended up desperately needing that present.
My stepfather, Jeff, loved reminding us he was the breadwinner of the house throughout our entire childhood. Anytime we sat down to dinner, he’d start with his usual spiel.

“You’re lucky I keep this roof over your heads,” he’d say and chortle. He also said it all the time while leaning back on his worn-out recliner. It was his favorite thing in the world.
My mom, Jane, always nodded along. She was the kind of woman who avoided conflict at any cost. She wasn’t raised in the 1950s, but her upbringing had been different from ours. Staying quiet had become almost an art form for her.
As her kids, my siblings (Chloe, Lily, and Anthony) and I could see that she desperately wanted to speak up but didn’t. Meanwhile, we surely didn’t consider him “the king of the castle” or a “real man,” which were other phrases Jeff used to describe himself.

Yes, he paid all the bills while we were growing up, and we were thankful. But that wasn’t an excuse to treat our mother like a servant and think he was better than the rest of us.
We had tried for years to get Mom to leave him to no avail.
Eventually, we all moved out of their house as we reached adulthood, but my sisters and I continued to visit Mom often. Anthony lived on the other side of the country, but he checked in every other day.

Still, we worried about her.
I felt that our visits weren’t enough to truly know what was going on in that house. I often sat alone in my apartment and wondered if Mom would ever leave this man and if there was something he could do to finally make her snap out of her proverbial shackles.
Yes, this is where it gets good.
This year, Jeff simply went too far. For days leading up to Mom’s birthday, he wouldn’t stop bragging about the “special gift” he’d picked out for her.

“This one’s going to knock her socks off,” he said over dinner at their house, grinning like a buffoon.
I wanted to believe him. Maybe he had finally decided to treat her with the respect she deserved. But deep down, I knew better. Jeff was Jeff, and people like him never changed.
My mom’s birthday arrived, and of course, my sisters and I were there, sitting in the living room. Jeff had a twinkle in his eyes, and I knew Mom had hope in hers.

After she opened our presents, my stepdad handed her a huge, beautifully wrapped package. He was smiling, and my mom’s face lit up as she carefully untied the ribbon.
“Oh, Jeff, you didn’t have to,” she said softly.
“Yes, I did. Go on. Open it,” he urged, leaning forward in his chair.
She unwrapped the box slowly, savoring the moment… until she saw what was inside— toilet paper. 12-pack. Four-ply. Jumbo rolls.

Mom blinked in confusion.
“It’s so soft. Just like you!” Jeff declared, slapping his knee and cackling. “And look, four-ply, to represent your four kids. Perfect, right?”
Mom let out a nervous laugh, but I could see her eyes glistening. My sisters and I exchanged a look. This wasn’t just a bad joke; it was cruel.
We’d had enough. We had to do something.

Two days later, our plan began to take shape. Jeff loved two things: being the “big man” and free food. So, we invited him to a “family dinner” at the Chinese restaurant he always raved about.
Chloe, my youngest sibling, was the one who planted the idea.
“We’ll do it in his favorite place. He won’t suspect a thing,” she said, smirking.
Lily, being the eldest and most practical, raised an eyebrow. “And what happens after?”
“Oh, don’t worry,” Chloe replied. “We’ll handle it.”

We set the date and made sure to hype it up, so Jeff wouldn’t miss it.
“Dinner’s on us this time,” Chloe told him sweetly
Jeff puffed out his chest. “Well, it’s about time someone else paid for once. I’m glad that being out of the house has finally opened your eyes to how great you fared because of me!”
We rolled our eyes internally.
The restaurant was bustling that night. Shiny red lanterns hung from the ceiling, giving the space a nice reddish glow.

The food from other tables smelled delicious, and I could tell Jeff was hungry as we sat down at our table.
“When are your mom and Lily getting here?” he asked, wrinkling his nose toward the front door.
“Don’t worry. They’ll be here soon. How about we order food anyway?” I suggested, nodding towards Chloe.
She agreed and started rattling off things she wanted, things we specifically planned to order: Szechuan beef, Kung Pao chicken, and the spiciest mapo tofu on the menu.

Jeff ordered his usual, but I knew what we had in mind would still work.
Each dish came out looking like a masterpiece of fiery reds and deep browns, garnished with fresh herbs and enough chili to make a grown man cry.
Chloe’s eyes twinkled as the waiter finished arranging everything on the table.
“Jeff, you can handle spicy, right?” she asked, pretending to be concerned.

Jeff stayed silent for a second, stumped, then nodded quickly. “I didn’t realize you gals wanted to share everything. Of course, I can eat anything. Nothing is ever too spicy for a real man.”
I chimed in with, “Be careful with these, though. They’re pretty hot.”
I just knew my words would make him mad.
“Don’t be ridiculous, Amelia,” Jeff scoffed and took his chopsticks to skewer a piece of beef straight into his mouth.

At first, he gave out an exaggerated moan, to “prove his manliness,” but soon, his face turned redder than the lanterns above us. Sweat beaded on his forehead as he chewed and breathed through his nose.
“Everything alright?” Chloe asked, again faking worry.
“Yes, yes,” he lied through his full mouth. “This is good stuff.”
I was sure Jeff wouldn’t grab more after gulping down an entire glass of Coke, but Chloe and I began eating in earnest.
“Oh, it’s not so spicy after all,” Chloe commented, smiling sugary-sweet. She was baiting him.

I nodded, grabbing more.
Not to be outdone, Jeff began to eat more. He was breathing roughly now, but when we asked if he was alright, he simply said, “This really clears the sinuses, gals.”
Still, his fingers went up and snapped at the waiter to bring him more Coke.
Chloe leaned over and whispered, “He’s going to feel that later.”
“Oh, definitely,” I whispered back, grinning conspiratorially.

While Jeff was busy showing off his “macho” tolerance for heat, Mom and Lily were busy back at the house with a rented U-Haul and movers.
They worked quickly to load up Mom’s belongings, such as clothes, keepsakes, her favorite chair, and even the toaster. I told them to take the things Mom had given Jeff over the years by saving up when she could: the recliner and his specialty tools.

But the pièce de résistance was Chloe telling them to remove every single roll of toilet paper in the house.

Jeff was still red when we left the restaurant, and he was grumbling about Mom and Lily being no-shows. So I just suggested going to the house to see if anything had happened.
When we arrived, everything was ready. The truck had already left. Meanwhile, Mom and Lily were hiding in the garage.
Jeff walked in with Chloe and me right behind him. He barely made it two steps into the living room before he froze.

“Where’s my recliner?” he barked, scanning the empty spot.
“Gone,” Chloe piped in casually, tilting her head. “Mom took what’s hers.”
Jeff turned to us and his face reddened again, but before he could say another word, his stomach gurgled loudly. He doubled over slightly, clutching his gut.
“Oh, man, I think that spicy food—” He paused, looking around frantically.

“Is something wrong, Jeff? I hope it wasn’t the food,” I said, blinking innocently.
He stared daggers at me before bolting down the hall. Moments later, we heard the bathroom door slam.
Lily and Mom appeared out of their hiding spot right in time to hear the sound of Jeff panicking. “What the hell? Where’s all the toilet paper?!” he yelled.
I couldn’t hold it in anymore.
“We took that along with the recliner!” I shouted, laughter bubbling up. “After all, it also belonged to Mom!”

“WHAT?” he shouted back.
It seemed like he wasn’t getting it, so Mom stepped closer to the bathroom door. “I’M LEAVING YOU, JEFF! And I took what was mine,” she exclaimed firmly. “Including my dignity.”
Jeff groaned loudly from behind the bathroom door. “You can’t just leave me like this!” he yelled.
“WATCH ME!” Mom replied, adding, “Not that you can right now, but enjoy staying in the bathroom all night!”

My sisters and I stared at each other, giggling.
Jeff groaned, and there were other unsavory sounds, which I took as our cue to leave. “Let’s go, Mom,” I said.
She nodded and walked out, thanking us.
***
The next day, Jeff tried to call her. Over and over again, he left voicemails full of fake apologies and pitiful excuses.
“Jane, come on, be reasonable! You can’t just run off like this!” he begged.

But Mom didn’t answer or call back.
Instead, Chloe had a better idea.
On his birthday, we sent Jeff a little gift. A jumbo pack of toilet paper, wrapped just as carefully as the one he’d given Mom.
Attached was a handwritten note that read: “For a real man.”

Mom moved in with Lily, a temporary arrangement where we all helped while she found a job. Anthony was delighted to learn about what we had done and wished he was there, too.
From what I hear, Jeff’s still complaining to anyone who’ll listen. But Mom is finally living her life without his control, and we couldn’t be prouder.
