This quick math puzzle asks you to solve 8 − 2 × 0 + 1.
The correct answer is 9.
Multiplication must be completed before subtraction or addition. First calculate:
2 × 0 = 0.
The expression then becomes:
8 − 0 + 1 = 9.
The trick is that people often rush through the equation from left to right. But the standard order of operations requires multiplication first.
Because anything multiplied by zero becomes zero, the middle term disappears. That leaves 8 + 1, which equals 9.
