Problem Statement
Simplify: 25 + 15 × 3 - 10 ÷ 2
Explanation
We must follow BODMAS or PEMDAS rule which stands for Brackets, Orders, Division, Multiplication, Addition, and Subtraction. This gives the correct order of operations.
Step 1: Multiplication: 15 times 3 equals 45. Step 2: Division: 10 divided by 2 equals 5. Step 3: Addition and Subtraction from left to right: 25 plus 45 minus 5 equals 70 minus 5 equals 65. Common mistake is solving left to right without BODMAS, which would give wrong answer.
