Arithmetic Operators and Variables
Arithmetic Operators
Arithmetic operators are used to perform mathematical operations on variables and
values. Here are the different types of arithmetic operators:
Addition (+): Adds two values together.
Subtraction (-): Subtracts one value from another.
Multiplication (*): Multiplies two values.
Division (/): Divides one value by another.
Modulus (%): Returns the remainder of a division operation.
Exponentiation (**): Raises a number to a power.
Floor division (//): Divides two values and returns the largest whole number.
Variables
A variable is a location in memory that stores a value. Here's how to declare and
assign a variable in Python:
variable_name = value
For example:
x = 7
y = 3
z = x + y
In this example, the variable z is assigned the value of x + y, which is 10.
Variables can be used with arithmetic operators to perform mathematical operations
on them. For example:
x = 5
y = 2
z = x / y
In this example, the variable z is assigned the value of , which is 2.5.
Note: Arithmetic operations with variables can produce decimal results, even if the
operands are integers. To get integer results, you can use floor division (//) or
modulus (%).
Summary
Arithmetic operators are used to perform mathematical operations on values and
variables. Variables are used to store and manipulate values. By using arithmetic
operators with variables, you can perform powerful mathematical computations.
