Formula and Explanation for This Calculator
This tool combines two common functions: basic arithmetic and percentage calculations. The formulas are straightforward and universally understood.
Basic Arithmetic Operations
The calculator uses standard mathematical operations. Depending on your selection, it will perform one of the following:
- Addition: Result = Value A + Value B
- Subtraction: Result = Value A – Value B
- Multiplication: Result = Value A * Value B
- Division: Result = Value A / Value B
Percentage Calculation
To find the percentage of a number, the formula is:
Result = (Percentage / 100) * Base Value
This is useful for quickly figuring out discounts, tips, or proportions. Our free online calculator makes this simple.
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Value A / Value B | The numbers used in an arithmetic calculation. | Unitless | Any real number |
| Percentage | The proportion of the base value to be calculated. | % | 0 – 100+ |
| Base Value | The total amount from which a percentage is calculated. | Unitless | Any real number |
