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!
Listening to the Echoes of Time: One Woman’s Mission to Preserve the Stories of the Elderly
The sterile scent of antiseptic hung heavy in the air as I navigated the maze-like corridors of the nursing home. I clutched a stack of donated blankets, a small gesture of comfort for the residents. As I rounded a corner, I came upon a heartwarming scene. A group of elderly residents, their faces a tapestry of wrinkles and age spots, sat in a circle, their eyes fixed on a young woman. She sat on a low stool, a small journal resting on her lap, her pen moving swiftly across the page.
“She comes every week,” a nurse whispered to me, her voice hushed. “None of them are her family.”
Intrigued, I watched from a distance. The residents, their voices frail and reedy, recounted stories of long-ago loves, childhood adventures, and wartime experiences. The young woman listened intently, her eyes filled with a gentle curiosity. She would occasionally pause, asking a clarifying question, her voice soft and soothing. As she listened, she meticulously recorded their words, capturing their memories in ink.
Later, I approached the young woman, thanking her for her kindness. “Many of them get no visitors,” she explained, her smile warm and genuine. “Their memories are fading, and I worry that their stories will be lost forever. So, I come here every week and listen. I write down their names, their life stories, the names of their loved ones, the places they’ve been, the things they’ve done. It’s a small thing, but I hope it helps them feel seen and heard.”
Her words struck a chord within me. In a world that often prioritizes the new and the shiny, it was easy to forget the importance of the past, the stories that shaped us. These elderly residents, with their fading memories, were a living archive of history, their lives a testament to the resilience of the human spirit. And this young woman, with her simple act of kindness, was ensuring that their stories would not be forgotten.
As I walked away, I couldn’t shake off the image of the young woman, her pen dancing across the page, capturing the essence of a life lived. Her actions were a powerful reminder that true compassion lies in the small, everyday gestures of kindness, in the act of simply listening and acknowledging the humanity of others.
The experience left me pondering the fleeting nature of time and the importance of preserving our memories. It made me realize that everyone has a story to tell, a legacy to leave behind. And sometimes, all it takes is a listening ear and a pen to ensure that those stories are not lost to the sands of time.
Later that day, I found myself reflecting on my own life, on the stories I wanted to tell, the memories I wanted to preserve. I started a journal of my own, a place to record my thoughts, my experiences, the joys and sorrows, the triumphs and failures. I wanted to make sure that my own story, however ordinary, would not be forgotten.
The young woman at the nursing home had shown me the power of empathy, the importance of connecting with others, and the enduring value of human connection. Her simple act of kindness had not only brought comfort to the elderly residents but had also inspired me to live a more meaningful life, one that valued the stories of others and cherished the memories that shaped us.
As I drifted off to sleep that night, I imagined the residents at the nursing home, their faces lit up with a sense of purpose as they recounted their lives to the young woman. I imagined their stories, their laughter, their tears, all preserved on the pages of her journal, a testament to their lives, a legacy for future generations. And I knew that in a small way, I too was contributing to the preservation of those stories, by sharing my own and by reminding myself of the importance of listening, of connecting, and of cherishing the memories that make us who we are.
The world, I realized, is filled with stories waiting to be told, with lives waiting to be remembered. And in the quiet moments, in the simple acts of kindness, we can all play a part in ensuring that those stories live on.
