Calculation Examples

See the calculator in action with these practical examples:

Basic Arithmetic
Calculate: (15 + 7) × 3 - 10
1. Parentheses first: 15 + 7 = 22
2. Multiplication: 22 × 3 = 66
3. Subtraction: 66 - 10 = 56
Result: 56
Percentage Calculation
What is 25% of 480?
1. Convert percentage: 25% = 0.25
2. Multiply: 480 × 0.25 = 120
Result: 120
Square Root
Find the square root of 169
1. Enter number: 169
2. Press square root button
3. Result: √169 = 13
Result: 13
Memory Function
Calculate: (12 × 8) + (15 ÷ 3)
1. First part: 12 × 8 = 96 (M+)
2. Second part: 15 ÷ 3 = 5
