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!
Joke of the day is the moment of relaxation you need to break the routine.
“Yesterday, I went to a hotel with my mistress, and at the entrance, I see my father-in-law’s car parked.
I lost all desire and, of course, if he saw me, I would have problems.
I explained to my mistress that today was impossible, and she left upset.
Out of frustration, I broke both mirrors and went home. The next day, I went to see him and laugh at the fact that his car had no mirrors. He was very upset, and I asked him:
What’s wrong with you? You seem upset.
How the hell wouldn’t I be? Yesterday, I lent your wife the car, and she brought it back without mirrors.”
Next joke
Dad, I want to get married!
First, apologize!
But why?
Just apologize!
What for? What did I do?
You need to apologize!
But why???
Apologize, I said!
Please, just give me a reason!!!
First, apologize.
Okay, dad… I’m sorry!
Perfect, now you’re ready! Your training is over. When you learn to apologize for no reason, then you can get married!
