Can You Solve This Tricky Viral Math Problem

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:

  1. Solve inside the parentheses: (1 + 2) = 3
  2. Rewrite the problem: 6 ÷ 2(3)
  3. Some then treated 2(3) as a single term and multiplied first: 6 ÷ 6 = 1

However, others applied division before multiplication:

  1. 6 ÷ 2 = 3
  2. 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).

  1. 6 ÷ 2 = 3
  2. 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

  1. Always follow the standard order of operations – PEMDAS (or BODMAS, if you learned it that way).
  2. If in doubt, add brackets – Parentheses make everything clearer and help prevent confusion.
  3. Be consistent – If you’re solving problems with others, use the same approach so that everyone gets the same answer.
  4. 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 Had Doubts about Dating a Single Dad, but What I Found after He Moved into My House Left Me Pale

I came home expecting a quiet evening, but what I found instead shook me to the core. In that moment, I realized my trust had been betrayed, and my peaceful life was about to be turned upside down.

When I first started dating Ryan, I knew there would be challenges. I was stepping into a relationship with a man who had three young daughters, and I was prepared for the extra noise, the mess, and the constant whirlwind that would follow us wherever we went.

I had been living alone in my cozy, peaceful home for years and had gotten used to the calm and order that came with it. But I knew that loving Ryan meant embracing the chaos his daughters would bring, and I was ready to make the necessary sacrifices.

My home was my sanctuary, but I was willing to adjust. When Ryan moved in, I sacrificed my guest room and the upstairs rec room so the girls could have their own spaces. It wasn’t always easy.

I would often find myself retreating to my bedroom just to get a moment of quiet. But I was committed to making our new family dynamic work, so I kept reminding myself that this was what it meant to love someone—sacrifices, compromises, and the willingness to adapt.

But just when I thought I had a handle on things, the situation took a turn I never saw coming.

Ryan’s ex-wife, Laura, had always been a bit of a wild card. She was the kind of person who thrived on drama and attention. So, when she suddenly decided to get the girls a dog, three kittens, and a bunch of rodents, I wasn’t entirely surprised.

What did surprise me was the fact that her lease strictly prohibited pets. I couldn’t understand why she would make such a reckless decision, knowing it would cause problems. But I chalked it up to her trying to win the girls’ favor, hoping they’d see her as the “fun” parent.

I thought that would be the end of it, that she’d have to face the consequences of her actions on her own. “She’ll sort it out,” I muttered, hoping Ryan would agree. But that wasn’t the case. When her landlord found out about the pets and threatened to evict her, Ryan stepped in, determined to play the hero. “They can stay with us,” he told the girls with a reassuring smile, “We’ll make room.”

“Are you serious?” I asked, my voice sharp with disbelief. “We can’t possibly take in all those animals, Ryan. You know I have allergies, we both work long hours, and let’s be honest, you’re not exactly the most reliable when it comes to keeping the house in order.”

He frowned, clearly taken aback. “But they’re just kids,” he pleaded. “They’ve already fallen in love with the animals. How can we take them away now?”

“I get that,” I replied, trying to stay calm. “But maybe a few of the rodents could stay, not the entire zoo. We can’t turn this place into a circus.”

The girls, overhearing our conversation, looked devastated. They had already become attached to the animals, and now they were faced with the possibility of losing them.

Ryan, caught in the middle, started sulking, his usual response when things didn’t go his way. Meanwhile, his ex, ever the drama queen, played the victim. She acted as if I was the evil stepmother ruining everyone’s fun, and that’s how the girls started to see me too.

Then, one afternoon, after a particularly exhausting day at work, I came home ready to unwind. As I pushed open the door, I froze. My living room looked like an animal shelter.

The dog was lounging on my couch, the kittens were scampering around like they owned the place, and the rodents were making themselves at home in the corners. My throat started itching almost immediately, my nose tingling with the telltale signs of an impending allergy attack.

I felt a surge of anger, betrayal burning in my chest. Ryan had brought all the animals over behind my back. As I stood there, trying to process what was happening, one of the girls, Emma, approached me, looking guilty.

She hesitated before blurting out, “Mom told us you wouldn’t mind the pets because you told her you liked animals. But when we were at dinner last week, I heard you tell Dad that you had allergies. I think Mom heard too.”

I didn’t react right away, just nodded and reassured her that it wasn’t her fault. But that was the first crack in the story I’d been told. Why was Ryan’s ex lying to her kids?

That’s when it clicked. Ryan’s ex had done this on purpose. She’d overheard me talking about my allergies and decided to use it against me, knowing it would cause chaos in our home. I was furious, but I also realized that I wasn’t going to let her get away with it.

That evening, I confronted Ryan. “Why did you bring the animals here without telling me?” I asked, my voice trembling with barely controlled anger.

He looked at me, guilt written all over his face. “I didn’t think it would be a big deal. The girls were so upset, and I just wanted to make them happy.”

“And what about me?” I shot back. “You know I have allergies. You know how hard it is for me to keep up with the housework as it is. Why didn’t you talk to me first?”

Ryan sighed, running a hand through his hair. “I’m sorry. I just… I didn’t want to disappoint them.”

I shook my head, feeling a mixture of anger and sadness. “Ryan, this isn’t just about the animals. It’s about trust. You went behind my back, and you let your ex manipulate you. We’re supposed to be a team, and right now, it feels like I’m fighting this battle alone.”

He looked at me, his expression softening. “You’re right. I should have talked to you first. I won’t let it happen again.”

But I wasn’t satisfied with just an apology. I needed to get to the bottom of what had really happened. I decided to dig deeper.

The next day, I made a few phone calls. It wasn’t hard to find the truth once I knew where to look. I managed to get in touch with her landlord under the guise of verifying some information about his other property. When I casually mentioned the pet situation, he was puzzled.

“I’ve never had a problem with pets,” he said. “In fact, I encourage it. Makes the place feel more like home, you know?”

That was all I needed to hear. Ryan’s ex had lied. She’d never been at risk of eviction. She’d used the pet issue as a way to manipulate the situation, knowing it would cause a rift between Ryan and me, and likely hoping I’d cave in to keep the peace.

That evening, I confronted Ryan again, this time with the full story. “I talked to her landlord,” I said, watching his face carefully. “He doesn’t have any problem with pets. She lied about being at risk of eviction.”

Ryan was floored. He stared at me, disbelief and anger flickering in his eyes. “She lied?” he asked, his voice barely above a whisper.

I nodded. “She used the situation to stir up trouble between us. She knew it would cause problems, and she did it anyway.”

Ryan clenched his fists, anger radiating off him in waves. “I can’t believe she would do that. I feel like such an idiot.”

I reached out, placing a hand on his arm. “You’re not an idiot, Ryan. But you need to see her for who she really is. We can’t let her manipulate us like this. We need to be stronger together.”

He looked at me, a mixture of regret and determination in his eyes. “You’re right. I’m sorry I didn’t see it sooner.”

The next day, I texted Ryan’s ex. I calmly explained that I knew the truth and that the animals needed to go back to her place. When she tried to argue, I reminded her that her own landlord had no issue with pets. She had no choice but to take them back.

The girls were understandably upset when they found out that their mom had lied to them about the pets. It wasn’t easy for them to reconcile that their mom had used them as pawns in her own game. But in the end, it brought some much-needed clarity to the situation.

Ryan and I had a serious talk about trust and communication. I made it clear that if we were going to make this work, we needed to be a team, making decisions together and not letting outside forces pull us apart. He agreed, and while things weren’t perfect, we were on the same page for the first time in a long while.
