Can you solve this without a calculator?
10 + 5 − 5 × 0 = ?
Answer: 15.
Use the standard order of operations. Multiplication comes before addition and subtraction, so calculate 5 × 0 first. That equals 0.
The equation now becomes 10 + 5 − 0.
Then work from left to right: 10 + 5 = 15, and subtracting 0 changes nothing.
The final answer is therefore 15.
The multiplication by zero is the part that causes most of the confusion, especially if someone starts solving the expression from the left without applying the correct order.
