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!
On a Trip with His Foster Family, Teenage Boy Runs Away to Find His Real Family after Spotting an Old Sign — Story of the Day
Sixteen-year-old Eric slips away from his foster family on a camping trip, desperate to find his real mother and the answers he’s always craved. But as he faces hard truths about the past and what family truly means, Eric’s journey takes a turn he never saw coming.
The Johnson family drove along the winding road, the car filled with excited chatter and Mila’s occasional giggles as she wiggled in her booster seat, her eyes wide with excitement.

Mr. Johnson glanced in the rearview mirror, catching Eric’s gaze and offering a warm smile. Eric tried to smile back, but he couldn’t shake the knot of worry in his chest.
He was almost sixteen now, and he understood his place in the family—or at least, he thought he did. The Johnsons had taken him in as their foster child when he was twelve. They’d told him he was family, even though he wasn’t their own child by blood.
For years, they’d treated him with a kindness he’d never known before, showing him what it felt like to be truly cared for. But now, with Mila—their own child—things felt different. Eric wondered if they’d still want him, now that they had a child of their own.

“We’ll stop here at the gas station; you can stretch your legs,” Mr. Johnson said, turning off the engine as they pulled over. Eric felt the cool air hit his face as he stepped out, and he lifted little Mila from her seat, setting her down gently. She clung to his hand, her tiny fingers gripping his tightly as she looked around with curiosity.
Eric’s gaze, however, was drawn to the other side of the road, where an old, weathered diner sign hung, faded and cracked. A strange feeling stirred in his chest as he looked at it, an odd sense of familiarity that he couldn’t place. He reached into his backpack, pulling out a worn photograph—the only thing left from his past, from his real parents.
In the photo, baby Eric stood beside a woman, his biological mother, with a sign in the background just like the one in the gas station.

Mrs. Johnson walked over, noticing Eric staring at something in his hand. “Everything alright?” she asked gently, her voice filled with warmth.
Eric quickly slipped the photo into his pocket, forcing a small smile. “Yeah, yeah, everything’s fine,” he replied, trying to sound casual.
Mr. Johnson called from the car, “Alright, family! Time to hit the road again.”
Eric took one last glance at the diner sign before getting back in the car with Mila and Mrs. Johnson.

Within an hour, they arrived at the campsite, a quiet, wooded area surrounded by tall trees and the sound of rustling leaves. Eric helped Mr. Johnson set up the tents, quietly going through the motions, his mind still on the photo.
After dinner by the campfire, Mrs. Johnson and Mila headed to bed. Mr. Johnson looked over at Eric. “Are you going to bed now?”
Eric shook his head. “I’ll stay up a bit longer.”
Mr. Johnson nodded. “Don’t stay up too late. Big hike tomorrow. You sure you’re okay, kiddo?”

Eric forced a smile. “Yeah, just not tired yet.”
“Alright,” Mr. Johnson said, giving him a reassuring pat on the shoulder before heading to bed.
Eric sat by the campfire, watching the last embers flicker, his thoughts drifting back to the photo he’d tucked away. He pulled it out once more, studying the faded image in the dim light.
Written neatly on the back were the words “Eliza and Eric.” The woman holding him had a faint smile, but he couldn’t remember her at all. Glancing over at the Johnsons’ tent, he felt a pang of guilt. They had always been kind, always treated him with care.

With a sigh, he slipped the photo into his pocket, went to his tent, and picked up his backpack. He checked through its contents—his few belongings, a bottle of water, and the sandwiches Mrs. Johnson had made for him.
She’d even cut the crusts off, remembering how he didn’t like them, just as she had when he first arrived at their home. Small acts like this made him feel seen, but still, he wondered if he truly belonged.
Taking one last look at the campsite, Eric turned and walked down the path toward the main road, the cold air biting at his cheeks.

It was pitch dark, and he switched on the flashlight on his phone, remembering how the Johnsons had handed it to him with a smile. “We need to know our kid is safe,” they’d said. If they really thought of him as their own, wouldn’t they have adopted him by now?
He walked along the road, shivering in the night air, his heart pounding with each step. After hours, he finally saw the dim lights of the diner.
Taking a shaky breath, he stepped inside, eyes adjusting to the gloomy interior. At the counter stood an old man, who looked at him with a frown as Eric approached, photo in hand.

The old man behind the counter narrowed his eyes at Eric. “We don’t serve kids here.”
“I don’t want anything to eat. I just have a question.” He pulled the photo from his pocket, unfolding it carefully. “Do you know this woman?”
The man took the photo, peering at it with a frown. “What’s her name?”
“Eliza,” Eric replied, hoping for a sign of recognition.

The man’s face shifted slightly, and he tilted his head toward a noisy group in the corner. “That’s her over there.” He handed back the photo, shaking his head. “She looked different back then. Life’s taken a toll.”
Eric’s heart pounded as he approached the table. He recognized the woman from the photo—older now, worn down, but definitely her. He cleared his throat. “Eliza, hi,” he said.
She didn’t respond, absorbed in her loud conversation.
Eric tried again, louder this time. “Eliza.”

She turned, finally noticing him. “What do you want, kid?”
“I…I’m your son,” Eric said quietly.
“I don’t have any kids.”
Desperate, he held up the photo again. “It’s me. See? Eliza and Eric,” he said.
“Thought I got rid of you,” she muttered, taking a long drink from a bottle.

Eric’s voice trembled. “I just wanted to meet you.”
Eliza looked him over with a smirk. “Fine. Sit down, then. Maybe you’ll be useful.” Her friends chuckled, and Eric sank awkwardly into a chair, feeling out of place.
After some time, Eliza looked around the diner, glancing toward the counter. “Alright, time to leave. Let’s get out before the old man catches on.”

The group started to stand up, gathering their things. Eric, feeling uneasy, looked at Eliza. “But you haven’t paid,” he said.
Eliza rolled her eyes. “Kid, that’s not how the world works if you want to survive. You’ll learn that,” she replied.
Eric hesitated, reaching into his backpack. He pulled out some cash, ready to leave it on the table, but before he could, Eliza snatched it from his hand and shoved it into her pocket.
As they headed toward the door, the old man behind the counter noticed. “Hey! You didn’t pay!” he shouted angrily.

“Run!” Eliza shouted, dashing out the door. The group bolted, and Eric had no choice but to follow. Outside, he noticed police lights flashing nearby. As Eliza ran past him, she shoved him, and he felt something slip from his pocket.
“Mom!” he called, desperate, hoping she’d turn back.
But Eliza didn’t stop. “I told you—I don’t have any kids!” she shouted over her shoulder, disappearing into the night.
A police car pulled up beside Eric. He stopped, knowing he couldn’t outrun them. The window rolled down, and one of the officers leaned out, squinting at him.

“Hey, isn’t this the kid they mentioned?” the officer asked his partner.
The other officer looked Eric over and nodded. “Yep, that’s him. Alright, kid, get in the car.”
Eric’s heart pounded. “I didn’t do anything wrong,” he said, his voice trembling. “I tried to pay, but she took my money. I can call my parents—they’ll come get me.”
He reached into his pocket, only to find it empty. Panic rose as he realized his phone was gone, too. Tears filled his eyes. “Please, you have to believe me. I didn’t do anything.”

One of the officers got out, placing a hand on Eric’s shoulder. “Come on, son.” Gently, he guided Eric into the backseat as Eric’s tears fell silently.
At the police station, Eric expected the worst, but instead, they led him to a small room with a warm cup of tea. Glancing up, his heart skipped when he saw the Johnsons talking with an officer nearby. Mila was in Mr. Johnson’s arms, and Mrs. Johnson looked worried, her eyes darting around the room.
The moment Mrs. Johnson spotted him, she gasped, rushing over and wrapping her arms tightly around him. “Eric! You scared us so much!” she said, her voice shaking. “We thought something terrible had happened when we saw you were gone. We called the police right away.”

Mr. Johnson approached, holding Mila close. “Eric, why did you run off like that?” he asked.
Eric swallowed, looking down. “I just… I wanted parents of my own. I thought finding my mom would change things, but she… she wasn’t what I thought,” he admitted.
Mrs. Johnson’s face softened as she squeezed his hand. “Eric, it hurts to hear that,” she said gently. “We consider ourselves your parents.”
Mr. Johnson nodded. “We’re sorry if we didn’t make that clear.”

Eric looked at them. “I thought… maybe you’d want to get rid of me now that you have Mila,” he confessed.
Mrs. Johnson pulled him into another hug, her arms warm and steady. “Parents don’t give up on their children, Eric.”
“You’re as much our child as Mila is,” Mr. Johnson added. “That’s never going to change.”
Eric’s tears fell, his heart finally feeling the love they’d always given. “This whole trip was actually for you,” Mr. Johnson explained. “You wanted to go camping, so we made it a special occasion.”

“A special occasion?” Eric asked, wiping his eyes.
“To tell you that we want you to officially be our son,” Mr. Johnson said with a smile.
“All the paperwork is ready, but only if you want it,” Mrs. Johnson added, her voice soft. Eric didn’t need to answer in words; he hugged them both, realizing he had found his real family.
