This math puzzle looks simple, but the order of operations is what matters.
The expression is:
9 + 2 × 0 + 1
Multiplication comes first:
2 × 0 = 0
Now finish the remaining addition:
9 + 0 + 1 = 10
A common mistake is to calculate from left to right or assume the ×0 makes the whole expression equal zero. It only affects the 2.
Answer: 10.
