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 Mother-in-Law Filled My Home with Cockroaches to Tarnish My Reputation as a Housekeeper – My Retaliation Was Severe

Elara thought marriage would be her happily ever after, until cockroaches invaded her home and her mother-in-law made her life a living nightmare. But when a dark secret blurred the line between victim and villain, Elara realized that revenge was the only way out.
I’m Elara, and I’ve been married to my husband, Jacob, for about a year now. Life, for the most part, has been good, really good, actually. We settled into married life with ease, enjoying the simple pleasures of being together.
Jacob is everything I could have asked for in a husband. He is kind, supportive, and always there when I need him. But, as with most things in life, there’s a catch.
That catch is my mother-in-law, Agnes.
From the very beginning, it was clear as day that she never liked me. Whether it was the way she looked at me or the not-so-subtle digs she made, her attitude was unmistakable. I’m not sure what I did to deserve her disdain, but it didn’t take long for me to realize that she saw me as an intruder in her son’s life.
Still, she’s Jacob’s mother, and for that reason alone, I’ve tried my best to live with it. To smile through her snide remarks and keep the peace, for Jacob’s sake. But no amount of forced smiles could prepare me for what came next.
Just when I thought I could handle her passive-aggressive digs, things took a turn for the worse.
For the past month, my house has felt like something out of a nightmare. No, scratch that. MY LIFE has felt like something out of a nightmare.
It started with a cockroach here and there. One scuttling across the kitchen counter. Another creeping along the bathroom floor.
But soon, they were everywhere. And I mean EVERYWHERE! The kitchen, the bathroom, the living room, hell, even our bedroom wasn’t safe. I’d wake up in the middle of the night feeling a tickle on my arm, only to flick on the light and see a roach making itself at home on my bed.
We called pest control multiple times. We bought traps, sprays, you name it. But no matter what we did, the roaches kept coming back, like they had some vendetta against me. And to top it all off, my mother-in-law just couldn’t resist rubbing it in.
“Honestly, Elara,” she’d say with that sickly sweet tone of hers, “you really should take better care of the house. Jacob deserves a clean home. How can you let it get this bad?”
It didn’t stop there. One afternoon, as she sipped tea in our living room, a roach had the nerve to crawl up the wall. Agnes’s eyes followed it with a look of exaggerated horror.
“My goodness, Elara,” she gasped, clutching her chest as if she were witnessing a crime. “I can’t imagine how embarrassed you must be, living in these conditions. I never had this problem when Jacob was growing up.”
Then there was the time she “helpfully” brought over a stack of cleaning supplies, dumping them on my kitchen counter with a too-bright smile. “I thought you could use these, dear,” she said, her voice oozing with false concern. “Maybe they’ll help you get a handle on things. I’d hate for people to think you can’t keep a clean house.”
Each comment was a jab, a twist of the knife, making me feel smaller and more inadequate every time. It was as if she reveled in my struggle, her words like salt in an already festering wound.
Every time she opened her mouth, it took everything in me not to scream. I’d nod, smile, and tell her I was doing my best, but inside, I was seething. This isn’t my fault, you old witch! I wanted to shout. But of course, I couldn’t do that. Not to Jacob’s mother.
But then, the universe threw me a bone. Or rather, Agnes made a mistake. She’d come over to “check on us” again, dropping her little barbs like confetti. As she left, she accidentally left her handbag on the couch. When I went to pick it up and move it, a receipt fluttered out. I wouldn’t have thought twice about it, but something caught my eye.
It was from a pet store. But not just any pet store—one that specialized in reptiles. And the item purchased? LIVE COCKROACHES!
My blood ran cold. For a moment, I just stood there, staring at that stupid piece of paper in my hand. And then, slowly, the realization hit me. Agnes was behind the infestation. She’d been sabotaging me, setting me up to look like the world’s worst housekeeper.
The anger that flared up inside me was blinding. I could feel it burning in my chest, my hands trembling with the force of it. But along with the anger came something else—something darker.
I wasn’t just going to confront her. No, that would be letting her off too easily. I was going to get revenge.
I stormed out of the house, receipt still clenched in my hand, and got into my car. I had no idea what I was going to do, but I knew I needed to strike back. Hard. As I drove, my thoughts raced, and then it hit me. I made a quick detour to that same pet store. If she wanted to play dirty, then I’d go nuclear.
Inside, I found exactly what I was looking for—a potent animal attractant. The kind hunters use to lure wild animals from miles away. The plan formed in my head like a beautiful, terrible flower, blooming with each passing second.
When I finally pulled up to Agnes’s house, night had fallen. She lived on the outskirts of town, right next to the woods, which made this perfect. I crept around her yard, spreading the attractant everywhere. The bushes, the flower beds, even the base of the house itself. I didn’t stop there.
I slipped inside — she always left the back door unlocked, trusting as ever — and sprinkled some inside too. The whole time, my heart raced with a mixture of fear and exhilaration.
By the time I finished, I was practically shaking with anticipation. I couldn’t wait to see what would happen. But for now, I went home, crawled into bed, and let sleep take me. And oh, how sweet that sleep was.
I dreamed of revenge, of Agnes’s horrified face, of the chaos I had unleashed, and I drifted deeper into that blissful darkness, savoring every second.
Then, just as I was reliving the final moments of my delicious payback, the shrill ring of the phone yanked me from my dream. I groggily reached for it, my heart pounding. It was Jacob, and from the frantic tone of his voice, I knew something big had happened.
“Elara, you won’t believe this,” he said, half laughing, half in shock. “Mom’s house was… attacked last night!”
I sat up in bed, trying to sound groggy. “Attacked? By who?”
“Not who—what. Animals. The whole yard was swarmed! Deer, moose, foxes, even birds! They trashed everything! They tore up the garden and broke the fences. And the smell… God, the whole place reeks. It’s like the animals turned the yard into their personal toilet.”
It took everything in me to keep from bursting out laughing. “That’s awful! What’s she going to do?”
“She’s coming to stay with us until it’s cleaned up. She doesn’t have a choice.”
I felt my stomach drop. Great, I didn’t think this through. But I couldn’t let him hear the panic in my voice. “Oh, okay. We’ll make it work.”
When Agnes arrived later that day, the look on her face was priceless. She was humiliated, furious, and worst of all, powerless. She barely acknowledged me as she walked inside, nose wrinkling at the sight of the cockroaches that still plagued our house.
“Oh, don’t mind them,” I said sweetly. “They just won’t go away, no matter what we do.”
I waited until later that night, after Jacob and I were alone, to show him the receipt. He stared at it, his face hardening as the truth sank in.
“She did WHAT?” he exclaimed, disbelief giving way to anger.
“Apparently, she’s been planting roaches in the house this whole time. I found this after she left yesterday,” I said, handing him the damning piece of paper.
Jacob stormed into the guest room, confronting Agnes right then and there. She tried to deny it, but the receipt was undeniable. She stammered out an apology, her face going red with shame.
“I didn’t think it would go this far,” she mumbled, eyes glued to the floor.
“Well, it did,” Jacob snapped. “And you’re paying for the pest control and all the damage you caused. Until it’s done, you’ll have to live among the cockroaches YOU brought into our lives.”
As I listened to their exchange, a smile tugged at the corners of my lips. Sure, I hadn’t planned on Agnes moving in, but at least now she was getting what she deserved.
Lying in bed that night, I felt a deep, dark satisfaction settle over me. Revenge might not always be sweet, but sometimes, it’s just what you need to get by. And as for Agnes? Well, let’s just say she’ll be sleeping with the roaches tonight.
And for many nights to come.
