Practical Examples
Example 1: Simple Expression
Expression: 6 + 4 × 3
Result:
- Multiply first → 4 × 3 = 12
- Then add → 6 + 12 = 18
Example 2: Expression with Parentheses
Expression: (6 + 4) × 3
Result:
- Parentheses → 6 + 4 = 10
- Multiply → 10 × 3 = 30
Example 3: Complex Expression
Expression: 20 − 5 × (2 + 3)
Result:
- Parentheses → 2 + 3 = 5
- Multiply → 5 × 5 = 25
- Subtract → 20 − 25 = −5
