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’m 18 and obsessed with using sunbeds… but people online are saying I look “burnt to a crisp.”
Megan Blain, an 18-year-old who’s hooked on sunbeds, says she won’t stop tanning, even though online trolls are constantly insulting her. They’ve compared her skin to a “dirty 2p coin,” but she feels stuck in a tanning habit she can’t break.
Megan, from Seaham, County Durham, started using sunbeds at 16 to keep a tan all year. She ditched fake tan products for daily sunbed sessions and even began using tanning injections to get a darker glow. Although she didn’t know much about the risks, she spent up to 30 minutes on sunbeds, sometimes using baby oil to boost the effect.
Teenager Megan Blain, 18, has admitted to being addicted to sunbeds, despite facing harsh criticism online and noticing concerning changes to her skin
Megan said, “I liked how I looked with a tan. I wear bright colors, and the tan made them stand out more. Once I saw how good it looked, I started going to the sunbeds more often.”
But her intense tanning routine has raised health concerns. Megan now admits she’s addicted and has tried to cut back on sunbed use.
She also says the tanning injections make her feel sick, and she’s noticed a strange patch on her skin that changes size. Even though she’s scared it could be cancer, she hasn’t stopped tanning yet. Megan has tried to go to the doctor several times but gets too nervous to go inside.
“I’m the type of person who worries about everything, so it’s strange that I’m not more worried about this patch. I know it could be melanoma, but I still use sunbeds, which shows it’s an addiction. I never feel dark enough,” she explained.
She says she’s stuck in a cycle of overusing sunbeds and taking injections that make her feel sick and unable to eat. She used to go every day, but now she goes about four times a week.
Despite getting negative attention from strangers, with some saying she looks like a “burnt chip” or a “cremated” version of herself, Megan still can’t imagine life without tanning beds.
Megan said, “Everywhere I go, people stare at me. When they say I’m dark, I don’t believe them. I don’t feel dark at all, like I can’t see it myself.”
She admits she wants to stop using sunbeds one day, but she can’t imagine quitting. “I wouldn’t recommend this to anyone because you could get addicted without even realizing it, like I did,” she warned.
Megan has tried to cut down, now only using sunbeds four times a week, and she’s using her TikTok platform to warn younger people about the dangers of sunbed addiction. She’s especially worried because more young people seem to be using sunbeds than older ones, and she knows how easy it is to get hooked.
However, Megan has also faced online trolls who make fun of her tan. Some compare her to “burnt chips” or say her skin looks like a dirty “2p coin.” One person even asked if the sunbeds “cremated” her.
While Megan’s views on tanning have changed, she still struggles to break her habit of using UV lights.
Megan said, “After two years, I’ve changed my mind about sunbeds. If I could go back, I’d never start. Now, it’s not even about wanting to be tan anymore—I just feel like I have to use them.”
She explained that once she’s on the sunbed, it’s hard to turn it off. “I don’t even like using them anymore, I actually dread it, but I feel like I physically can’t stop.”
Another tanning addict, Fionnghuala Maguire, 35, from Belfast, shared her story, saying she feels “lucky to be alive” after using sunbeds almost every day for 15 years. She started at 14 and never used sunscreen during that time. Fionnghuala is now warning others not to make the same mistake, having been hooked on tanning and going to salons up to seven days a week at the height of her addiction.
