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 and His Mom Ate All the Food I Cooked for Me and the Kids
Life has been hectic since welcoming our youngest, Dylan, four months ago, joining his three siblings all under eight. Juggling their needs has been exhausting yet profoundly fulfilling.
Becoming a mother has defined my life’s purpose. Initially planning to return to work after a year, I chose full-time motherhood with each child’s arrival reinforcing my decision.
However, tensions grew with my mother-in-law’s unwelcome visits. After a chaotic day, she crossed a line by consuming our children’s dinner, prompting a confrontation that led to her and George leaving.
This pivotal moment marked my decision to file for divorce, prioritizing my children’s and my own well-being. With unwavering support from my family, I’ve embraced this new chapter, teaching my kids self-respect and resilience.
