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 MIL Turned Our Adopted Son’s Room into Her Reading Room While We Were Away — the Lesson I Taught Her Was Harsh

My mother-in-law’s secret makeover of our adopted son’s room sparked a family firestorm. What unfolded next rocked our world, exposing raw nerves and hidden truths. It’s a wild ride of love, betrayal, and unexpected lessons that changed us all – for better or worse.
I spent weeks getting Max’s room just right. The excitement of finally adopting our son had Garrett and me buzzing with energy. We hung posters of dinosaurs and spaceships, carefully arranged stuffed animals, and filled bookshelves with colorful stories.

“Do you think he’ll like it?” I asked Garrett, stepping back to admire our work.
“He’s going to love it, Nora,” Garrett replied, wrapping an arm around my waist. “This room is perfect for our little guy.”
Our moment was interrupted by a knock at the door. Vivian, Garrett’s mother, poked her head in. “My, my, what a… vibrant space,” she said, her lips pursed.
I forced a smile. “Thanks, Vivian. We wanted Max to feel welcome.”

Vivian’s eyes scanned the room again, a calculating look crossing her face. “You know,” she mused, “this space would make a lovely reading nook. I’ve been longing for a quiet place to enjoy my books.”
She paused, then added with a condescending smile, “Perhaps I could even use it to read some advanced literature to Max. Heaven knows the boy could use some intellectual stimulation to improve his… potential.”
I exchanged a worried glance with Garrett. Her casual suggestion and thinly veiled insult felt like an attempt to claim the space for herself, disregarding Max’s needs entirely.

It was becoming clear that Vivian’s presence in our home was causing more tension than comfort, and I couldn’t shake the feeling that this was just the beginning of our troubles.
Garrett cleared his throat. “Mom, we’ve talked about this. Max is our son now, and we’re doing what’s best for him.”
Vivian waved a dismissive hand. “Yes, yes. I just think blood is thicker than water, that’s all.”
I bit my tongue, reminding myself that Vivian was still grieving her husband’s passing. She’d been living with us since he died, and we thought it would help her cope. Now, I wasn’t so sure.

“Well, we should finish packing,” I said, eager to change the subject. “Our anniversary trip is tomorrow.”
“Oh yes, your little getaway,” Vivian said. “Are you sure it’s wise to leave the boy so soon?”
“Max will be fine with my sister Zoe,” I assured her. “It’s just for a few days.”
The next morning, we said our goodbyes. Max clung to me, his dark eyes wide with worry. “You’ll come back, right?” he whispered.
My chest tightened. “Of course we will, sweetheart. We’ll always come back for you.”

Zoe arrived to pick him up, and we waved until they were out of sight. As we got in the car, I noticed Vivian watching from the window, her expression unreadable.
Our trip was lovely, full of romantic dinners and long walks on the beach. But I couldn’t shake a nagging feeling of unease.
“Do you think everything’s okay at home?” I asked Garrett one night.
He kissed my forehead. “I’m sure it’s fine. Let’s try to enjoy our time away, okay?”
I nodded, pushing my worries aside. Little did I know what was waiting for us when we got back.

As soon as we stepped through the front door, I knew something was off. “Do you smell paint?” I asked Garrett, frowning.
His eyes widened. “Yeah, I do. What the —”
We raced upstairs, my stomach dropping with each step. When we reached Max’s room, I froze in the doorway, unable to believe my eyes.

Gone were the colorful posters and toys. In their place were floor-to-ceiling bookshelves, a plush armchair, and a delicate daybed. The walls were a soft beige, erasing any trace of the vibrant blue we’d chosen.
“What the hell happened here?” Garrett exclaimed.
Vivian appeared behind us, beaming. “Oh good, you’re home! Do you like the surprise?”
I spun around, fury building inside me. “Surprise? You call this a surprise? Where are Max’s things?”

“Oh, I packed them away,” Vivian said, waving her hand. “I thought it was time to give the room a more sophisticated touch. The boy needs to grow up, after all.”
“He’s seven years old!” I shouted. “This was his safe space, and you destroyed it!”
Garrett put a hand on my arm. “Mom, how could you do this without asking us?”
Vivian’s smile faltered. “I… I thought you’d be pleased. This room is much more practical now.”

“Practical?” I sputtered. “It was perfect the way it was. Where is Max supposed to sleep? Where are his toys?”
“The daybed is perfectly suitable,” Vivian insisted. “And he has too many toys anyway. It’s time he learned to appreciate literature.”
I could feel myself shaking with rage. Garrett must have sensed I was about to explode because he quickly said, “Mom, we need some time to process this. Could you give us a moment?”
After Vivian left, I collapsed onto the daybed, trying to hold back tears. “How could she do this?” I whispered.

Garrett sat beside me with a sigh. “I don’t know. This is way out of line, even for her.”
I took a deep breath, an idea forming in my mind. “I think it’s time we taught your mother a lesson about boundaries.”
Garrett raised an eyebrow. “What do you have in mind?”
Over the next few days, I pretended everything was fine. I smiled at Vivian, thanked her for her “thoughtfulness,” and even asked her advice on decorating.

All the while, Garrett and I were plotting our revenge.
On Saturday morning, I said to Vivian, “We’d love to treat you to a day at the spa today and serve you a special dinner tonight,” I said, injecting warmth into my voice. “We want to thank you properly for all you’ve done.”
“Oh, how lovely!” Vivian replied.
As soon as Vivian left, Garrett and I sprang into action.

We spent the day transforming Vivian’s beloved garden into a children’s playground. We dug up her prized roses to make room for a sandbox, scattered toys everywhere, and even installed a small slide.
When she returned, I greeted her at the front door with a bright smile. “We have a surprise for you,” I said, holding out a blindfold.
She hesitated. “A surprise? What kind of surprise?”
“You’ll see,” Garrett said, gently tying the blindfold around her eyes. “We think you’re really going to love it.”
We led her outside into the backyard, positioning her in front of her transformed garden. “Ready?” I asked, barely containing my excitement.
“I suppose so,” Vivian said, sounding nervous.

I removed the blindfold. For a moment, there was silence. Then Vivian let out a strangled gasp.
“What… what have you done?” she cried, staring at the chaos before her.
I adopted an innocent tone. “Oh, we just thought the garden needed a more playful touch. Don’t you like it?”
“Like it?” Vivian sputtered. “You’ve destroyed my sanctuary! My beautiful roses, my carefully tended beds… all ruined!”
“We didn’t destroy it,” Garrett said calmly. “We simply repurposed it. You know, like you did with Max’s room.”

Vivian’s face paled as understanding dawned. “This… this is about the boy’s room?”
“His name is Max,” I said firmly. “And yes, this is about his room. How do you think he’ll feel when he comes home to find his safe space gone?”
“I… I didn’t think…” Vivian stammered.
“Exactly,” Garrett cut in. “You didn’t think about how your actions would affect our son. Just like we didn’t consider how this would affect your garden.”
Vivian’s lower lip trembled. “But my garden was so important to me. It was my… my —”

“Your sanctuary?” I finished for her. “Just like Max’s room was his sanctuary. Do you understand now?”
Tears welled up in Vivian’s eyes. “I’m so sorry,” she whispered. “I never meant to hurt anyone. I just… I felt like I was losing my place in this family.”
Garrett’s expression softened. “Mom, you’ll always have a place in our family. But Max is our son now, and you need to accept that.”
“Can we go inside and talk about this?” Vivian asked, wiping her eyes.

We spent the next few hours having an honest, sometimes painful conversation. Vivian admitted her fears about being replaced, especially after losing her husband. We acknowledged that we could have done more to include her in our new family dynamic.
By the end of the night, we had a plan. We would restore Max’s room together, and Vivian would help us explain to Max what happened. She also agreed to start seeing a grief counselor to work through her feelings about losing her husband.
The next day, we all pitched in to bring Max’s room back to life. As we hung the last poster, we heard the front door open.

“Mom? Dad? I’m home!” Max called.
We exchanged nervous glances as his footsteps pounded up the stairs. When he burst into the room, his face lit up with joy.
“You kept it the same!” he exclaimed, throwing himself into my arms.
Over his head, I caught Vivian’s eye. She gave me a small, sad smile, and I knew we were on the path to healing.
That night, we all crowded into Max’s room for a bedtime story. As I looked around at my family, I realized that sometimes, the hardest lessons lead to the greatest understanding.
