This math puzzle looks simple, but the correct answer depends on following the order of operations.
The expression is:
18 + 6 × 0 + 1
Multiplication comes first:
6 × 0 = 0
Now complete the remaining addition:
18 + 0 + 1 = 19
The ×0 only affects the 6. It does not make the entire expression equal zero, which is where many people go wrong.
Answer: 19.
