This math puzzle looks simple, but the order of operations decides the correct answer.
The expression is:
13 + 3 × 0 + 2
Multiplication comes first:
3 × 0 = 0
Now complete the addition:
13 + 0 + 2 = 15
The ×0 only affects the 3, not the entire expression. That small detail is what can easily lead to the wrong answer.
Answer: 15.
