Classic brain training methods are perhaps puzzles like crosswords or sudoku, but in recent times I have become more and more attracted to the type of challenge you’ll see below.

These types of 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 tests are more fun when you find yourself trying to remember the math you learned as a child.

Can you find the correct number?

Okay, here comes the challenge.

In the picture below, you will face a math problem, and there are three different possible solutions you can pick from.

Which of the answers do you think is right?

A

B

C

ANSWER:

Let’s break it down carefully so there’s no trick involved.

We start with:

40+40×0+1

Step 1: Follow the order of operations

Multiplication comes before addition (PEMDAS/BODMAS).

So we handle:

40×0=0

Step 2: Substitute back into the expression

Now it becomes:
40 + 0 + 1

Step 3: Add from left to right

40 + 0 = 40
40 + 1 = 41

Final Answer: 41

So the correct choice is B) 41.
