Practical Examples
Example 1: Simple Expression
Expression: 10 + 5 × 2
Result:
- Multiply first → 5 × 2 = 10
- Add → 10 + 10 = 20
Example 2: Expression with Parentheses
Expression: (10 + 5) × 2
Result:
- Parentheses → 15
- Multiply → 15 × 2 = 30
Example 3: Complex Expression
Expression: 25 − 3 × (4 + 1)
Result:
- Parentheses → 5
- Multiply → 3 × 5 = 15
- Subtract → 25 − 15 = 10
