# Class 11:Python Arithmetic operators

Arithmetic operators

Arithmetic operators are used to performing mathematical operations like addition, subtraction, multiplication, etc.

 Operator Meaning Example + Add two operands or unary plus x + y+2 – Subtract right operand from the left or unary minus x – y-2 * Multiply two operands x * y / Divide left operand by the right one (always results into float) x / y % Modulus – the remainder of the division of left operand by the right x % y (remainder of x/y)>>> 10%64>>> 10%73>>> 10%31 // Floor division – division that results into the whole number adjusted to the left in the number line x // y>>> 5//22>>> 5/22.5 ** Exponent – left operand raised to the power of right x**y (x to the power y)print(2**3)8Print(3**2)9

Example:1

```a=10
b=20
c=a+b
print("Sum ",c)
c=a*b
print("Prod ",c)
c=a-b
print("Diff ",c)
c=(a+b)/2
print("Avg ",c)```

Output:

```Sum 30
Prod 200
Diff -10
Avg 15.0
>>>```

Example:2

```print(10%3)
print(20%2)
print(20%3)
print(10%6)
print(20%6)```

Output:

```1
0
2
4

>>>```

Example:3

```#1
print(10/3)
print(10//3)
#2
print(20/8)
print(20//8)
#3
print(20/3)
print(20//3)
#4
print(45/4)
print(45//4)```

Output:

```3.3333333333333335

Example:4

```a=10**2
print(a)
a=5**2
print(a)
print(10**3)
print(5**3)```

Output:

```100
