This quick math puzzle is all about the order of operations.
The expression is:
4 + 5 × 0 + 5
Multiplication comes first:
5 × 0 = 0
Now the expression becomes:
4 + 0 + 5 = 9
Answer: 9.
The zero only affects the term being multiplied. It does not turn the entire expression into zero. Once the multiplication is handled first, the rest is simple addition.
