Mathematical Formulas Used in the Operations Calculator
Each operation follows a specific mathematical formula.
1. Addition Formula
Addition combines two or more values to find their total.
Formula:
Result = First Number + Second Number
Example:
First Number = 25
Second Number = 15
Calculation:
25 + 15 = 40
Result:
40
2. Subtraction Formula
Subtraction calculates the difference between two numbers.
Formula:
Result = First Number – Second Number
Example:
First Number = 50
Second Number = 18
Calculation:
50 – 18 = 32
Result:
32
3. Multiplication Formula
Multiplication calculates the product of two numbers.
Formula:
Result = First Number × Second Number
Example:
First Number = 12
Second Number = 5
Calculation:
12 × 5 = 60
Result:
60
4. Division Formula
Division determines how many times one number is contained within another.
Formula:
Result = First Number ÷ Second Number
Example:
First Number = 100
Second Number = 20
Calculation:
100 ÷ 20 = 5
Result:
5
Important Note:
Division by zero is not mathematically possible. If the second number is zero, the calculation cannot be completed.
5. Modulus Formula
The modulus operation calculates the remainder after division.
Formula:
Result = First Number % Second Number
Example:
First Number = 17
Second Number = 5
Calculation:
17 ÷ 5 = 3 remainder 2
Result:
2
Modulus is commonly used in programming, number theory, and checking whether numbers are even or odd.
6. Power Formula
The power operation calculates exponential values.
Formula:
Result = First Number ^ Second Number
or
Result = First Number raised to the Second Number
Example:
First Number = 3
Second Number = 4
Calculation:
3⁴ = 81
Result:
81
