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!
I Was the Only One Who Went to My Grandma’s Birthday Brunch — After Seeing Her Tears, I Taught My Family a Lesson
My story begins badly but ends on a positive note. It’s about my Gran-Gran, the sweetest lady alive, who raised me and my brothers during our parents’ divorce. Ahead of her 83rd birthday, she surprised us by organizing a brunch at her place, despite her deteriorating health, making her own bread and pastries, and sending handwritten invites.
On her birthday, I arrived 10 minutes late to find her cleaning up alone. She admitted, “Sany, you aren’t too late, no one bothered showing up on my birthday. But it’s okay, sweetheart. I know everyone is busy.” My heart broke. Everyone had promised to be there, but none showed up. I hugged her and decided to take action.v
I lied to my family, saying Gran-Gran had fallen and was in the hospital, convincing them to send money for hospital bills. I collected a significant amount and used it to book a trip for Gran-Gran and me to a beach resort she’d always wanted to visit. We spent a week enjoying the sun, the sea, and each other’s company. I shared the trip images on social media, tagging all our family members.
When we returned, Gran-Gran was glowing. “Thank you for this, darling. It’s been the best week of my life,” she said. From that day on, my family never missed another event. They showed up for every birthday, holiday, and Sunday dinner. Every time I saw Gran-Gran’s happy face, I knew it had all been worth it. Do you think I overreacted and took things too far?
