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 Accidentally Discovered My Husband’s Cheating through an IG Post — My Public Yet Dignified Revenge Shook His World


During her seemingly joyous baby shower, Lora exposes her husband’s infidelity through a slideshow that shocks not only him and his mistress but also family and friends gathered under the guise of celebration. Follow along with this dramatic unmasking that not only shatters the facade of a happy family but also sets the stage for a decisive and meticulously planned fallout.
As I watched the soft morning light filter through the curtains, I cradled our six-week-old daughter, Lily, in my arms.
It was just another quiet morning, except it wasn’t. Tom was packing his suitcase again for the first time since Lily was born.
Before, his frequent travels were just a part of our routine—I’d kiss him goodbye and count the days until his return. But this time, everything felt different.
“Are you sure you have everything?” I asked, trying to keep my voice steady as Tom moved around our bedroom, gathering his belongings.
“Almost ready, Lora. I just need to grab a few more things,” Tom replied, his voice calm and reassuring. He glanced at Lily, sleeping peacefully against my chest. “I know this is hard. It’s just a week.”
A week. Seven days might not seem long, but to a new mom still figuring out how to juggle sleepless nights and endless diapers, it felt like an eternity.
“I just… I’ve never been alone with her, not really. What if I do something wrong?” My voice cracked slightly with the weight of my unspoken fears.
Tom stopped and sat next to us on the bed. He took my hand in his, squeezing gently. “Lora, you’re doing amazing. Honestly, you’re a natural at this. And hey, I’m just a phone call away, okay?”
I nodded, attempting a brave smile. “I know. It’s just—all those nights we talked about teamwork and now, suddenly, I have to do this solo.”
“We are still a team,” he reassured me, brushing a kiss on Lily’s forehead. “No matter where I am, we’re in this together.”
As he zipped up his suitcase, the reality of the impending solitude pressed down on me. I wasn’t just scared; I was terrified of being alone, not for my sake, but for Lily’s. What if she needed more than I could give?
Tom pulled us into a hug, his suitcase standing at the door like an unspoken barrier. “It’s going to be okay,” he whispered. “We’ll get through this. We always do.”
And with that, he was gone. I watched his car disappear around the corner and closed the front door gently behind me.
The rest of the day passed in a blur of feedings, diaper changes, and tender moments trying to soothe Lily’s fussing. By the time her cries finally gave way to sleep, the sun had set, leaving a calm evening to unfold.
I walked to the kitchen, poured myself a cup of hot chocolate, and sat on the balcony of our bedroom to unwind. It was my moment of respite, a brief pause in the constant demands of new motherhood.
I picked up my phone and opened Instagram, eager to immerse myself in something other than chores and diapers—a much-needed escape into the virtual world.
I scrolled through the vibrant pictures, catching glimpses of lives uninterrupted by the relentless needs of a newborn. Deep down, I felt a pang of longing—for the days when spontaneity was a given, not a luxury.
That’s when I stumbled upon our local celebrity, Anna Wren’s page, and without a second thought, I began browsing through her latest posts, unaware of the shock that was about to hit me.
She was celebrating at a new high-end restaurant downtown, her smile as radiant as the flash on the camera. The caption boasted about a night out with friends, a reminder of the world outside my baby-centric universe.
I zoomed in on the photo to admire the restaurant’s chic decor—a blend of modern and vintage that gave it a cozy yet elegant vibe. That’s when I saw them. In the softly blurred background, unmistakable even from a distance, was Tom.
He was sitting across from a woman, engaged in what looked like an animated conversation. I squinted, my heart pounding as recognition dawned.
It was Eliza, his university friend—the one who had never hidden her disdain for me. The one he had assured me was just a friend, someone I shouldn’t worry about.
The hot chocolate turned cold in my hands as I stared at the screen, my mind racing. Why hadn’t he told me about meeting her?
He was supposed to be on a business trip, confined to meetings and solo dinners, not cozy catch-ups with old friends who clearly didn’t think much of his wife.
Feeling a mix of anger and betrayal, I took a screenshot of the image. My next steps were unclear, but I knew I needed to confront him. This wasn’t just about his whereabouts; it was about trust, about the reality of our partnership now tested by distance and silence.
My mind was a tangled mess of emotions as I replayed the scene from Anna’s Instagram over and over. Tom, my husband, the father of our daughter, was on more than just a business trip. He was out there betraying our family.
But I wasn’t going to let my shock cloud my judgment. I needed to be strategic, meticulous.
First, I confirmed the hotel where Tom was staying by matching it with Anna’s tags about her influencer event. I had to be sure, absolutely sure.
So, I called my friend Mia, who had never met Tom. I asked her to do something that felt straight out of a spy movie—go to the hotel and take photos discreetly.
The pictures she sent back left no room for doubt: there was Tom and Eliza, unmistakably close, holding hands, kissing—a bitter confirmation of my worst fears.
The urge to confront him was overwhelming, yet I chose to wait. I planned every move with precision, as if setting up dominoes.
Quietly, I began funneling money into a separate account, knowing I might need every penny for what was coming. I met with a divorce attorney to understand my rights and the implications, especially concerning our newborn daughter, Lily.
His next business trip was my opportunity. I sent a bouquet of flowers to Tom’s hotel room with a note, carefully imitating Eliza’s handwriting, “Thank you for a wonderful evening, I can’t wait for many more.”
It was subtle but sharp, a dagger cloaked in velvet. The flowers were timed to arrive when Eliza was likely with him, planting seeds of doubt and paranoia.
When Tom returned, I kept my composure as if nothing had changed. Yet, under the calm surface, I was orchestrating the final act of my plan.
I suggested a belated baby shower, a seemingly innocent celebration with our close friends and family. I insisted we invite Eliza, claiming it would be nice to finally connect with his friends from Uni.
Tom, surprised by my suggestion, hesitantly agreed.
The day of the shower, our home filled with laughter and light chatter, a stark contrast to the storm brewing inside me. As guests cooed over Lily and exchanged pleasantries, I prepared the last piece of my revenge.
Midway through the event, I started a slideshow—cute photos of Lily, her milestones, and us as a new family. I even threw some in there with Tom’s extended family members.
Then, as the room hummed with warmth, the images shifted. There on the screen was the Instagram photo of Tom and Eliza in the background, unnoticed until now. The room fell silent. The next photos were Mia’s—clear shots of Tom and Eliza’s intimate moments.
The reaction was immediate and visceral. Whispers erupted around the room; Tom’s face drained of color, turning him ghostly pale. Eliza, caught in the glaring truth, stood up abruptly, her chair scraping loudly against the floor as she rushed out, humiliated.
The aftermath was chaotic. The room was still buzzing with the murmurs of our stunned friends and family as Tom turned to me, desperation etching his features. “Lora, please, let me explain. It’s not what it looks like,” he pleaded, his voice cracking under the strain.
I looked at him, my expression steady and resolute. “Save it, Tom. There’s nothing you could say to change what I saw. What we all saw.”
“But Lora—”
“No,” I cut him off firmly. The decision was made. “I’ve heard enough, Tom. Your actions spoke louder than your words ever could.”
I turned away from him, addressing the room briefly. “Thank you all for coming today. I think it’s best if we end the gathering now.”
As the guests slowly filed out, the whispers of disappointment and sympathy followed them out the door. Once everyone had left, I dialed my attorney, the evidence of Tom’s betrayal clear and undeniable. “I want to proceed with filing for divorce,” I informed her, my voice steady, backed by a painful certainty.
“Understood,” my attorney replied. “I’ll prepare the necessary paperwork. We have everything we need.”
Days later, the fallout continued. Tom’s parents, having learned of the incident, invited him over. I wasn’t there, but I heard about it from Tom later, his voice hollow. “We can’t believe you would do something like this,” his mother had said, disappointment heavy in her tone.
“We’re removing you from our will. You need to think about the consequences of your actions, especially how they affect your daughter.”
Tom recounted the meeting to me over the phone, a note of disbelief in his voice. “They’re serious, Lora. I’ve lost everything.”
“Yes, Tom,” I replied, my tone devoid of warmth. “You have.”
Whatever came next, I knew we would face it together, just me and my Lily, and that was enough.
