Subtraction of Numbers using Lambda Function

>>>sub= lambda a, b: a – b
>>>print(sub(18,6)

Output would be
6

>>>print(mul(18,6)

Output would be
108

Division using Lambda Function

>>>div= lambda a, b: a / b
>>>print(div(18,6)

Output would be
2.0

Computing Square of a Number using Lambda Function

>>>square= lambda a: a * a
>>>print(square(5)

Computing Mean of three Numbers using Lambda Function
