Python math functions

print(a+b)          # 17 , sum of two numbers 
print(a-b)          # 7 , subtraction  of two numbers 
print(a*b)          # 60, product of two numbers 
print(a/b)          # 2.4, quotient of two numbers 
print(a//b)         # 2 , floored quotient   
print(a%b)          # 2,  remainder of division 
print(a**b)         # 248832, a to the power b 
print(pow(a,b))     # 248832, a to the power b 
print(divmod(a,b))  # (2,2) ,the pair (a // b, a % b)
