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!

Our Granddaughter Called Us Stingy Because of Her Wedding Gift from Us

This time, we sent an air fryer to our youngest granddaughter, the cheapest thing on her registry. Eloise called us, livid, accusing us of being cheap. I remember picking up her call and she didn’t even say hi, she just started ranting, “Seriously, Grandma? I just got your gift. An air fryer? That’s the cheapest thing you could find on my registry!”

I was taken aback because as much as the air fryer was the cheapest on their registry, I still thought it’d be useful to them, so I told her that. Eloise kept on complaining, “Useful? Come on, you know you can do better than that. Everyone knows you have the money. I just can’t believe you’d be this cheap with me. It’s embarrassing.”

In this heated moment, I told her, “Yes, you’re right. We are cheap, old, and useless. The only thing you DIDN’T know is that the day before the wedding, we were going to gift you a check for $40,000.”

I revealed this in an attempt to explain to Eloise about the cash gift we usually give our grandkids before the wedding but she was so angry at this point, that she wasn’t listening to a thing I said. I speculated that maybe she didn’t believe we would gift her such an amount of money after only buying her an air fryer.

Eventually, she said, “No, it’s clear. You just don’t love me enough to show it. You know how much pressure I’m under with the wedding. And then, this? It’s like you don’t even care,” then she hung up.

Despite my husband and I’s shock at Eloise’s reaction, we then bought her a China set, hoping to appease her, but decided against giving her the $40,000, feeling she hadn’t earned it.

Fast forward to last week. Eloise talked to her brother and found out that we were telling her the truth about the money. After confirming it with her cousins, she, called again, accusing us of discrimination, “I just found out that it’s true you gave the money to everyone else when they got married. Why didn’t I get anything?”

We stood firm, explaining our stance was due to her initial reaction, “We felt after your reaction to the wedding gift, it wasn’t right to go ahead and gift you the money.” Eloise pleaded trying to convince us otherwise, “So, you’re punishing me? Is that it? Because I was upset about an air fryer?”

I was angry that she didn’t even understand what she did wrong. “It wasn’t about the air fryer, Eloise. It was how you spoke to us, the disrespect. That’s not something we expected or can support,” I explained.

Eloise implored us, nearly in tears, “But that’s so unfair! I was stressed, Grandma. Planning a wedding is hard, and I just snapped. I didn’t mean any of it.” I felt like she should have only apologized to us instead of finding excuses to justify her behavior.

However, I told her, “We understand that it’s a stressful time, but actions and words have consequences. We hoped you’d understand the value of family and love over material things.” Full of desperation, Eloise added, “But you don’t understand! Can’t we just forget all this happened? I need that money, Grandma.”

She pleaded, threatened to boycott Christmas, and accused us of cutting her off but we didn’t budge. In the end, I expressed, “We love you very much. This has nothing to do with cutting you off. We just hope you’ll reflect on this and understand why we made our decision.”

Now, Eloise has followed up on her threat and she’s boycotting Christmas. Her mother, who is our daughter-in-law, is siding with her, calling us unreasonable. However, we feel that after all we have done for Eloise, the air fryer gift, shouldn’t have triggered this reaction.

For context, we had already paid for her college, and her parents covered her graduate school and half the wedding. Additionally, she and her husband are financially comfortable and do not desperately need our money.

We’re also not upset with our grandkids for revealing the cash gift since she is among the group of family members who are allowed to know about it. Our reason for sending the air fryer earlier was that we live far away, so we always send our gifts early.

The wedding gift is also separate from the money, which we give with the hope it will be used for something significant, like a home. Now, we feel like the action we took towards Eloise was well deserved and we are not going back on our decisions even if she and her mom threaten to do their worst.

Despite the tumultuous events and Eloise’s refusal to understand our perspective, my husband and I stand by our decision. Love and respect in our family are paramount, and we hoped this situation would be a learning experience for her.

The holidays might be quieter this year with her family’s absence, but our hope is for healing and understanding in the future. Our door and hearts remain open to Eloise, whenever she’s ready to mend fences.
