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+b
Example:
- 10 + 5 = 15
2. Subtraction (−)
Subtraction finds the difference between two numbers.
Formula:Result=a−b
Example:
- 20 − 8 = 12
3. Multiplication (×)
Multiplication is repeated addition.
Formula:Result=a×b
Example:
- 6 × 4 = 24
4. Division (÷)
Division splits a number into equal parts.
Formula:Result=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.
