Understanding Basic Arithmetic Operations
Arithmetic operations form the foundation of mathematics. Let’s explore each operation in detail.
Addition (+)
Addition combines two or more numbers to produce a total.
Formula
A+B=Result
Example
10+15=25
Real-Life Uses of Addition
- Shopping totals
- Budget calculations
- Score tracking
- Financial planning
Subtraction (-)
Subtraction finds the difference between two numbers.
Formula
A−B=Result
Example
50−20=30
Real-Life Uses of Subtraction
- Expense tracking
- Measuring loss
- Comparing values
- Inventory management
Multiplication (×)
Multiplication is repeated addition.
Formula
A×B=Result
Example
8×5=40
Real-Life Uses of Multiplication
