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!

With a blend of nerves and resolve shimmering in her gaze, the young girl tentatively entered the luminous spotlight. The megastar handed her the microphone with a gentle query, «Do you know ‘You Raise Me Up’?» A wave of cheers engulfed the arena,
Summoning courage from the depths of her being, the little girl nodded, her voice as delicate as a whisper yet as potent as a symphony, filling the expanse of the arena with the opening strains of the cherished melody. In that instant, a collective gasp of awe rippled through the crowd—a fusion of astonishment and reverence, marveling at the prodigious talent housed within such a tender frame.
