#Operators

#1. Arithmetic operators +,-,*,/,//,remainder %,power of i.e ^3 ^4of **
n1=10
n2=3
n3=4

print(n1/n2, "\n") #results plus remainder
print(n1//n2, "\n") #results minus remainder
print(n1%n2, "\n") #gives remainder only
print(n1 ** n3, "\n") #power of^3 of

#2. Comparison Operator (bool) gives True or False<,>,<=,>=,==,!=

#6. Logical Operators and,or, nor
