Python Arithmetic Operators

Python Arithmetic Operators are used to perform mathematical operations like addition, subtraction, multiplication, and division.

Arithmetic Operators in Python

There are 7 arithmetic operators in Python. The lists are given below:

Operator	Description	Syntax
+	Addition: adds two operands	x + y
–	Subtraction: subtracts two operands	x – y
*	Multiplication: multiplies two operands	x * y
/	Division (float): divides the first operand by the second	x / y
//	Division (floor): divides the first operand by the second	x // y
%	Modulus: returns the remainder when the first operand is divided by the second	x % y
**	Power (Exponent): Returns first raised to power second	x ** y

Precedence of Arithmetic Operators in Python

Let us see the precedence and associativity of Python Arithmetic operators.

Operator	Description	Associativity
**	Exponentiation Operator	right-to-left
%, *, /, //	Modulos, Multiplication, Division, and Floor Division	left-to-right
+, –	Addition and Subtraction operators	left-to-right

Python Arithmetic Operators Examples

Addition Operator

In Python, + is the addition operator. It is used to add 2 values.

Python3

val1 = 2
val2 = 3

# using the addition operator
res = val1 + val2
print(res)

Output: 

5

Subtraction Operator

In Python, – is the subtraction operator. It is used to subtract the second value from the first value.

Python3

val1 = 2
val2 = 3

# using the subtraction operator
res = val1 - val2
print(res)

Output:

-1

Multiplication Operator

Python * operator is the multiplication operator. It is used to find the product of 2 values.

Python3

val1 = 2
val2 = 3

# using the multiplication operator
res = val1 * val2
print(res)

Output : 

6

Division Operator 

Python // operator is the division operator. It is used to find the quotient when the first operand is divided by the second.

Python3

val1 = 3
val2 = 2

# using the division operator
res = val1 / val2
print(res)

Output:

1.5

Modulus Operator

The % in Python is the modulus operator. It is used to find the remainder when the first operand is divided by the second. 

Python3

val1 = 3
val2 = 2

# using the modulus operator
res = val1 % val2
print(res)

Output:

1

Exponentiation Operator

In Python, ** is the exponentiation operator. It is used to raise the first operand to the power of the second. 

Python3

val1 = 2
val2 = 3

# using the exponentiation operator
res = val1 ** val2
print(res)

Output:

8

Floor Division Operator

The // in Python is used to conduct the floor division. It is used to find the floor of the quotient when the first operand is divided by the second.

Python3

val1 = 3
val2 = 2

# using the floor division
res = val1 // val2
print(res)

Output:

1
