Arithmetic is the branch of mathematics that deals with numbers and their operations. The four basic arithmetic operations are:

Addition

• Definition: Combining two or more numbers to get a total (sum).
• Symbol: +
• Example: $25+15=40$
• Applications: Adding money, calculating totals, counting items.

Subtraction

• Definition: Finding the difference between two numbers.
• Symbol: -
• Example: $50-20=30$
• Applications: Calculating change, comparing values, measuring differences.

Multiplication

• Definition: Repeated addition of a number.
• Symbol: ×
• Example: $6\times 4=24$
• Applications: Area calculation, scaling quantities, business profits.

Division

• Definition: Splitting a number into equal parts.
• Symbol: ÷
• Example: $20÷5=4$
• Applications: Sharing items equally, per capita calculations, ratios.

Order of Operations (BODMAS Rule)

When solving complex problems, follow BODMAS:

• Brackets
• Orders (powers, roots)
• Division
• Multiplication
• Addition
• Subtraction

Example: $25+5\times (27÷3)-9=61$

Real-Life Applications

• Finance: Budgeting, calculating interest, expenses.
• Education: Solving math problems, exam preparation.
• Business: Profit/loss analysis, inventory management.
• Daily Life: Shopping, cooking measurements, time management.

Conclusion

Mastering basic arithmetic operations is essential for success in academics, careers, and everyday life. Addition, subtraction, multiplication, and division form the backbone of mathematics and are applied in countless real-world scenarios.
