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 Daughter-in-Law Tossed My Belongings Out After Finding Out She Inherited the House, but Karma Came for Her That Very Day
The finality hit me when I turned to leave.
Dad was truly gone. I tightened my grip on the box as if holding onto it could somehow keep him with me. When I reached my car, silent tears were slipping down my cheeks.
I sat in the car and cried until my tears ran out. My phone beeped and rang several times, but it was just Matt. He was probably worried about me, but some grief you have to wade through alone.
The last thing I expected to find when I arrived home was my whole life strewn across the front lawn like some kind of unholy estate sale.
The wind picked up, scattering the memories I’d so carefully packed into boxes and hauled down from the attic.
Mom’s old recipes, her china, the worn plaid quilt Dad used to nap under, and all his books — it all lay out in the open, unprotected, as if they meant nothing. I stumbled out of my car, heart pounding.
“What in God’s name…” I muttered, my voice swallowed by the wind.
“Oh, good. You’re finally back. I was getting tired of waiting.”
There, perched on my patio furniture with her designer sunglasses and her too-bright lipstick, was Jessica. My daughter-in-law didn’t even glance up from her phone. She took a leisurely sip from her coffee, and her lips curved in a barely restrained smirk.
“Jessica… What is all this?” My eyes swept over the chaos, disbelief clamping down on my chest. “What are you doing?”
She glanced up, lowering her sunglasses just enough for me to see the disdain in her eyes. She waved a manicured hand dismissively.
“I’m doing what’s necessary. This is my home now, after all.”
A cold knot twisted in my stomach. “Your home? What are you talking about?”
“Looks like you should’ve attended the will reading.” Jessica held up a crisp piece of paper, and there was my father’s signature, clear as day, at the bottom. “Guess your dad knew who deserved it most, huh?”
I swayed, gripping the car door for support. “That’s impossible. Dad would never—”
“Oh, but he did.” She smirked, casually inspecting her perfect manicure.
“Signed, sealed, delivered. The house is mine now.” She leaned in close, her perfume, a cloying, artificial scent, invading my space. “I think it’s time you moved on, Hattie.”
A truck rumbled into the driveway, and my son, Matt, climbed out, his face twisting as he took in the scene. His boots crunched over the gravel as he approached, confusion deepening the crease between his brows.
“What the heck, Jess? First you run out of the lawyer’s office, and now you send me this weird text? What’s going on?” he asked, glancing from me to Jessica, his jaw tight.
She stretched, standing at last, looking smug and at ease in her towering heels. It made my skin crawl. “Like I said, I’m making some necessary changes, honey. And actually, there’s more you should know.”
Matt’s expression hardened with a flash of something I hadn’t seen before. “More than you throwing my mother’s belongings all over the yard?”
“Much more!” Jessica’s laugh was harsh. “I want a divorce.”
The word hung in the air like the final nail in a coffin. Matt’s mouth opened, then closed as he struggled to process. “What? You can’t be serious.”
“Oh, I am.” Her voice was dripping with disdain. “I’ve spent enough years suffocating in this house, being made to feel like I don’t fit in, like I’m not good enough!” She gestured at the house with a sweep of her arm. “I need a fresh start.”
“You have no right—” I started, but she cut me off with a scornful wave.
“Oh, save it, Hattie. You never wanted me in this family. You looked down on me right from the start, judging me just because I didn’t grow up with a silver spoon. Well, now I’m finally getting what I deserve out of you people.”
Matt’s face shifted from bewilderment to anger, his fists clenched. “Everything my family said about you is true,” he said, voice low and trembling. “You really are a covetous witch.”
Jessica’s veneer cracked.
“And you’re a spineless mama’s boy!” she snapped. “Always running to her defense, always putting her first.” She sneered, pointing a perfectly manicured finger at him. “It’s pathetic. You’re just as small-minded as she is.”
“Don’t you dare talk about my son that way!” My voice cut through the silence, sharper than I’d intended.
“I’ll do whatever I want, Hattie.” Jessica set her hands on her hips, her expression smug. “And there’s nothing either of you can do about it.”
“In fact,” Jessica continued. “The two of you had best hurry and clear your stuff off MY lawn, before I call the cops and have them arrest you both.”
“Are you out of your mind?” Matt yelled.
I numbly looked on as Matt confronted Jessica. None of this made sense! Dad hadn’t even liked Jessica! My hands shook as I pulled out my phone and quickly dialed Dad’s lawyer.
His voice was a balm, calm and reassuring. “Hattie? I was just about to call you.”
“… really believed I liked you?” Jessica yelled in the background. “You were just a means to an end, a way for me to leave my old neighborhood behind. Now I have the house, I don’t need you anymore!”
“Please,” I whispered to the lawyer. “Tell me she’s lying. There’s no way Dad left his home to Jessica.”
There was a pause, then a warm chuckle.
“You’re right. Your father didn’t leave her the house. It was all a test to get her to show her true colors.”
“A…test?” Relief rushed through me, and I started laughing, tears gathering in my eyes. It was the kind of laugh that came from somewhere deep, a laugh that surprised even me.
Jessica’s face twisted, her confidence faltering. “What are you laughing at?”
“Oh, Jessica,” I managed, still shaking. “You really should have waited for the real will reading.”
“What?”
I let the satisfaction roll through me as I explained. “Dad never left you the house. It was fake — a test to get you to show your true character.”
Matt turned to Jessica, his face a storm of emotions. “Looks like Grandpa’s plan worked.”
Jessica’s eyes widened. She glanced between Matt and me as the realization of what she’d done sunk in. Her confident facade crumbled, her voice turning desperate as she scrambled to save face.
“Matt — baby, please.” She reached out, but he recoiled, the finality in his eyes unmistakable.
“I swear, I never meant it!” She pleaded. “I was just…upset, frustrated. You know I love you!”
He shook his head. “Save it. You want a divorce? You’ve got one.”
As Jessica stomped off the property, her heels sinking with each step, I felt an odd peace settle over me. Dad’s wisdom lived on, a quiet, guiding presence.
Matt and I gathered the remnants of my life from the grass, and I couldn’t help thinking that sometimes the real inheritance isn’t in a house — it’s in the lessons of who truly deserves to be in your life.
Dad would have been proud.
