This quick math puzzle asks you to solve 11 + 2 × 0 + 1.
The correct answer is 12.
Multiplication must be completed before addition, so first calculate:
2 × 0 = 0.
The expression then becomes:
11 + 0 + 1 = 12.
The common mistake is to calculate from left to right without respecting the order of operations. Because anything multiplied by zero becomes zero, the middle term disappears completely.
If you answered 12, you followed the standard rule correctly.
