Arithmetic Operations in Python

In Python, you can perform basic arithmetic operations using the + (addition), - (subtraction), * (multiplication), and / (division) operators.


Addition​

Use the + operator. a + b represents the sum of a and b.


Subtraction​

Use the - operator. a - b represents the result of subtracting b from a.


Multiplication​

Use the * operator. a * b represents the product of a and b.


Division​

Use the / operator to divide one number by another. This operation always returns a float, even if the result is a whole number. a / b represents the value obtained by dividing a by b.


Let's look at a simple example to see how each operation works.

Example of Number Operations
a = 10
b = 5

# Addition
print("Addition:", a + b)  # Output: 15

# Subtraction
print("Subtraction:", a - b)  # Output: 5

# Multiplication
print("Multiplication:", a * b)  # Output: 50

# Division
print("Division:", a / b)  # Output: 2.0

Operator Precedence​

Just like in standard arithmetic, operations inside parentheses are performed first in Python.

Additionally, multiplication and division have higher precedence than addition and subtraction in Python expressions.

Operator Precedence Example
a = 10
b = 5

print("Operator Precedence:", a + b * 2)  # Output: 20

print("Operator Precedence:", (a + b) * 2)  # Output: 30
