This short math puzzle asks you to solve 10 − 10 × 0 + 10. The numbers are simple, but the order of operations matters.
The correct answer is 20.
Multiplication comes first, so calculate 10 × 0. That equals 0. The expression then becomes 10 − 0 + 10.
Now work from left to right: 10 − 0 = 10, and 10 + 10 = 20.
So the full calculation is: 10 − (10 × 0) + 10 = 20.
A common mistake is to subtract 10 from 10 before doing the multiplication. Standard arithmetic rules do not allow that here. Complete multiplication first, then finish the subtraction and addition.
