Challenge: Can you solve this math problem for middle schoolers – without a calculator?
Classic brain training methods are perhaps puzzles like crosswords or sudoku, but I have recently become more attracted to the type of challenge you’ll see below.
These puzzles have been flooding the web lately, probably because they are really fun!
These are old classic mathematical problems. When you were in middle or high school.
These math problems are more fun when you find yourself trying to remember the math you learned as a child.
Can you figure out the correct solution?
Here is the challenge, in the picture below.
At the top of the picture, we see the task and then four possible answers.
Which solution do you think is the correct one?
How did you come up with it?
Take your time and think about it to find the correct solution.
Done? Below you can check if you picked the right number!
A
B
C
The correct answer
The correct answer is B: 12.
Why is 12 the correct answer?
Well, if you remember from your school days, according to the order of operations, you do multiplication before addition and subtraction, so you start by solving 3 x 3, which results in 9.
Then we are left with a simpler math problem: 3 + 9 – 3 + 3
The answer is therefore 12.
Did you pick the correct number? Congratulations!
My Husband Didn’t Meet Me at the Hospital Discharge with Our Newborn – When I Found Out His Reason, I Went Pale
When Sarah welcomed a bouncing baby boy, she thought it would be the happiest day of her life. But an unexpected betrayal shattered her world, leaving her devastated and alone. She packed her bags and left with their newborn, forcing her husband to confront his priorities.
A few weeks ago, I gave birth to our beautiful baby boy, Luc. It was a tough pregnancy, filled with sleepless nights and constant worry, but it was all worth it the moment I held Luc in my arms.
The plan was simple: my husband, Tom, would pick us up from the hospital and we’d start our new life as a family. I imagined him cradling Luc, his eyes lighting up with joy. That image kept me going through the hardest days.
The day of our discharge arrived, and I was buzzing with anticipation. I had Luc wrapped in a cozy blanket, and every tiny sound he made filled my heart with warmth.
I kept glancing at the clock, each minute dragging longer than the last. Tom was supposed to be here by now. I checked my phone: no missed calls, no messages. My excitement began to twist into anxiety.
The nurse placed a comforting hand on my shoulder. “If you need anything, don’t hesitate to call the hospital,” she said softly.
“Thank you,” I whispered, my voice barely audible as I stepped inside, feeling more alone than ever.
I needed Tom to understand the gravity of what he had done. My heart pounded as I methodically packed a bag for me and Luc. Each item I placed in the suitcase felt like a nail in the coffin of my trust.
Tom truly was a changed man. He stepped up and became the supportive partner and loving father I knew he could be. He never missed an important moment again, whether it was a midnight feeding or a precious first smile. His priorities were in order, and he made sure we knew we were his world.
