This math puzzle looks simple, but the correct answer depends on following the order of operations.
The expression is:
12 − 7 × 0 + 1
Multiplication comes first:
7 × 0 = 0
Now complete the remaining calculation:
12 − 0 + 1 = 13
The ×0 only affects the 7. It does not make the entire expression equal zero, which is where many people get caught.
Answer: 13.
