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 Sister Tried to Set Me up with a Bridesmaid Dress, but She Didnt Expect I would Fix It
This story is such a rollercoaster of sibling rivalry, heartbreak, and eventual reconciliation! It perfectly captures how deep-rooted insecurities and misunderstandings can create tension between siblings. Sadie’s pranks and cruelty toward Nancy clearly stemmed from her own feelings of inadequacy and jealousy, though that doesn’t excuse her behavior. The turning point with Aunt Marie’s intervention is brilliant—Nancy is empowered without stooping to Sadie’s level, which gives the story a satisfying twist.
It’s powerful to see how a moment of vulnerability from Sadie, after her plan backfired, led to her apology. It makes the reconciliation feel genuine, despite all the past hurts. Their eventual reconnection shows how time and a little nudge from someone like Aunt Marie can help heal old wounds. This story shines a light on how complex and layered sibling relationships can be, especially when there’s a history of competition and resentment.
It feels like a story that offers hope for anyone who’s struggled with sibling rivalry—do you think their new chapter will last?
