Computation Calculator Formulas Explained
Each calculation uses a specific mathematical formula. Understanding these formulas helps users know how the results are generated.
1. Square Formula (x²)
The square of a number means multiplying the number by itself.
Formula:
Square = x × x
Where:
- x = original number
Example:
Find the square of 8.
8² = 8 × 8
8² = 64
Result: 64
Squares are commonly used in geometry, algebra, statistics, and scientific calculations.
2. Cube Formula (x³)
The cube of a number means multiplying a number by itself three times.
Formula:
Cube = x × x × x
Example:
Find the cube of 4.
4³ = 4 × 4 × 4
4³ = 64
Result: 64
Cube calculations are used in volume measurements, physics, engineering, and mathematical modeling.
3. Square Root Formula (√x)
A square root is the value that produces the original number when multiplied by itself.
Formula:
√x = y, where y × y = x
Example:
Find the square root of 81.
9 × 9 = 81
Therefore:
√81 = 9
Result: 9
Square roots are frequently used in geometry, statistics, and scientific calculations.
4. Factorial Formula (x!)
Factorial is the multiplication of all positive whole numbers from 1 up to a given number.
Formula:
n! = n × (n-1) × (n-2) × ... × 1
Example:
Find 5 factorial.
5! = 5 × 4 × 3 × 2 × 1
5! = 120
Result: 120
Factorials are widely used in:
- Probability
- Statistics
- Combinations
- Permutations
- Computer science
Note: Factorials are only calculated for non-negative whole numbers.
5. Double Formula (2x)
Doubling a number means multiplying it by two.
Formula:
Double = 2 × x
Example:
Double 15.
2 × 15 = 30
Result: 30
Doubling is commonly used in finance, measurements, and everyday calculations.
6. Half Formula (x ÷ 2)
Finding half means dividing a number into two equal parts.
Formula:
Half = x ÷ 2
Example:
Find half of 50.
50 ÷ 2 = 25
Result: 25
Half calculations are useful in:
- Sharing quantities
- Discounts
- Measurements
- Data analysis
7. Percentage Formula (10% of Number)
The calculator can find 10% of any number.
Formula:
10% = Number × 0.10
Example:
Find 10% of 500.
500 × 0.10 = 50
Result: 50
Percentage calculations are commonly used for:
- Discounts
- Taxes
