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%6 4 >>> 10%7 3 >>> 10%3 1
//	Floor division – division that results into the whole number adjusted to the left in the number line	x // y >>> 5//2 2 >>> 5/2 2.5
**	Exponent – left operand raised to the power of right	x**y (x to the power y) print(2**3) 8 Print(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:

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:
