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!
My Wife Found Sweaters She Knitted for Our Grandkids at a Thrift Store – She Was So Heartbroken, I Had to Teach Them a Lesson

I just discovered that occasionally extreme tactics are necessary to get your message across to someone. Grounding my grandchildren for what they did to my wife wasn’t going to be a sufficient lesson in this case. I set them a challenging task to ensure their redemption. I, Clarence (74), have always thought my wife Jenny (73), is the loveliest and most kindhearted person. This was particularly true with regard to our grandchildren. She knits them exquisitely detailed sweaters every year for their birthdays and Christmas. She puts all of her heart into this tradition. She would frequently begin new initiatives more earlier than necessary.

This was done to guarantee that every child received a unique item created particularly for them. She would make the kids stuffed animals for their birthdays. Maybe a blanket for the grandchildren who are older. We just had a trip and decided to stop by our neighborhood thrift store last week. For our landscaping project, we were trying to find some old-fashioned pots. What was supposed to be a relaxing trip became an unforgettable, heartbreaking experience!Something I wish we could take back from our shared history. My wife stopped as we were browsing the aisles. Her gaze fixed on something, causing her to momentarily stop. “What the heck is that? She questioned, gesturing with a quivering finger, “Am I seeing things? The sweaters she had crocheted for our grandchildren were hanging there among a gazillion other trashed stuff! All of them were for sale! Among them, there was a blue-and-grey-striped one that was definitely the one Jenny made for our oldest grandchild last Christmas.

\It was clear from the expression on her face. She stretched out and caressed the fabric softly, and her heart broke. She tried to hide her pain with a grin and a repression of tears. Her voice was barely audible as she said, “It’s okay, I understand that kids might be embarrassed to wear grandma’s sweaters.” I could hardly contain my emotions as I drew her closer for an embrace, realizing how hurt she was. No, this wasn’t acceptable, and unfortunately for our family, my wife was more understanding than I was. They committed a heartless, destructive, and blatantly cruel act! Even though she maintained her composure, I couldn’t help but feel furious! Once I was sure she was asleep, I went back to the thrift store that evening and bought back everything she had made! I had made up my mind to put this right. I made the decision to impart a significant life lesson to our grandchildren without even speaking to my wife! One that would instill in them the value of showing gratitude for future blessings. I made a package for each grandchild the following day. I put wool, knitting needles, and a basic set of knitting instructions inside each. I added a picture of the sweater they had thrown away along with a severe note that said, “I know what you did.” You had better start knitting your own gifts now!”Grandma and I are coming for dinner, and you better be wearing her presents,” I said in my note. Alternatively, I’ll notify your parents and you won’t receive any further gifts for birthdays or Christmas. As one could guess, there was a wide range of reactions! A few of the grandchildren apologized sheepishly over the phone. They acknowledged that they were unaware of the significance of these gifts. Some remained mute, maybe feeling awkward or not knowing what to say. But the point had been made. When dinnertime finally arrived, there was a palpable sense of excitement. Our grandkids arrived one by one. All of them wearing the sweaters that nobody thought were worthy. To be very honest, some of the art they produced was absurdly poor! The one short design and one long hand made me chuckle uncontrollably! Some sweaters were obviously dropped mid-project, while others were simply too large! Not a single reproduction could have done MY Jenny’s original work justice. When sincere regret was expressed through their apologies, the tension subsided. Our oldest grandchild stated to their parents, “We are so sorry for taking your gifts for granted, Grandma,” while their parents watched. “We swear never to give away anything you’ve lovingly made for us ever again.” They made an attempt at knitting. They became aware of the passion and work that went into every stitch as a result. “Our oldest grandchild admitted that this was harder than he had anticipated, Grandpa.”

He continued tugging at the sleeves of his hurriedly constructed attempt as he spoke. Another person said, “Yeah, I’m sorry, Grandma,” with wide eyes. “It took me hours to finish one section of a scarf!” Bless her heart, my wife pardoned them, giving each one her customary warmth and compassion. “I’m amazed you got them to do this much!” Jenny loved our grandchildren and turned to face me. I needed to take action, my darling. I couldn’t allow them to believe that your gifts were just throwaway objects. I knew I had made the right decision when we embraced and she opened her warm heart to me. The laughter increased and the mood lightened as we ate dinner. This difficult lesson bonded everyone. It served as a helpful reminder of the importance of recognizing and appreciating one another’s work. Ultimately, our grandchildren gained knowledge about love, respect, and the elegance of a handcrafted gift in addition to learning how to knit a basic stitch. My wife felt better when she saw that her efforts were eventually recognized. I discovered how much of an impact she had on bringing our family together. The grandchildren added one more thing as we were wrapping up our dinner: “We promise to cherish our handmade gifts forever.” A promise that brought my wife more warmth than any sweater could have! I said to them, “I have one last surprise for you all,” before I left. I ran to the car and returned with a bunch of big plastic bags. “Open them,” I told our grandchildren. When they discovered every sweater Jenny had given them, they were all beaming with happiness. When they transitioned from their awful attempts at knitting to the flawless sculptures my wife had made them, they were like completely different persons. “Grandma and grandpa, thank you so much!” they exclaimed as they gave us a warm hug before we left. The spouse of a woman in the following tale was in need of some important life lessons. Before she put her foot down, he had developed the poor habit of making purchases—big and small—without getting her approval.
