What are Basic Calculations?

Basic calculations include

  • Addition
  • Subtraction
  • Muliplication
  • Division

Order of Operations

The order of operations determines the sequence in which calculations are performed:

  1. Brackets (Solve anything in parentheses first)
  2. Multiplication/Division
  3. Addition/Subtraction

This ensures accurate results when combining different operators in a calculation.

Python Examples

num1 = 10
num2 = 20
num3 = 30

average = (num1 + num2 + num3) / 3

print(average)  # Output = 20
