A simple math problem is confusing millions online because most people solve it the wrong way.
The equation looks easy:
3+3\times3-3+3
Many people quickly answer 18 by solving from left to right:
3 + 3 = 6
6 × 3 = 18
18 − 3 = 15
15 + 3 = 18
But that ignores the order of operations.
Using PEMDAS/BODMAS rules, multiplication must come before addition and subtraction.
So first solve:
3 × 3 = 9
Now the equation becomes:
3 + 9 − 3 + 3
Then solve left to right:
3 + 9 = 12
12 − 3 = 9
9 + 3 = 12
The correct answer is 12.
The puzzle went viral because it tricks people into relying on instinct instead of mathematical rules. It’s a reminder that even simple-looking equations can become confusing when we rush through them.
