Mathematical Operations Explained

This calculator performs four basic arithmetic operations. Let’s understand each one.


1. Addition (+)

Addition combines two numbers to find their total.

Formula:Result=a+bResult = a + bResult=a+b

Example:

  • 10 + 5 = 15

2. Subtraction (−)

Subtraction finds the difference between two numbers.

Formula:Result=abResult = a – bResult=a−b

Example:

  • 20 − 8 = 12

3. Multiplication (×)

Multiplication is repeated addition.

Formula:Result=a×bResult = a \times bResult=a×b

Example:

  • 6 × 4 = 24

4. Division (÷)

Division splits a number into equal parts.

Formula:Result=a÷bResult = a \div bResult=a÷b

Important Rule: Division by zero is not allowed.

Example:

  • 20 ÷ 5 = 4

Real-Life Example of Calculator Usage

Let’s say you are managing daily expenses:

  • You spent $150 on groceries
  • You spent $75 on transportation

To find total expenses:

150 + 75 = 225

Now suppose you want to split this expense between 3 people:

225 ÷ 3 = 75

This shows how useful basic arithmetic can be in everyday life.
