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(3**2)

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:
