# Simple Calculator

# adds two numbers 

def add(x, y):

   return x + y

# subtracts two numbers 

def subtract(x, y):

   return x - y

# multiplies two numbers

def multiply(x, y):

   return x * y

# divides two numbers

def divide(x, y):

   return x / y

print("Select the operation to perform.")

print("1. Addition")

print("2. Subtraction")

print("3. Multiplication")

print("4. Division")

# Tinf input

elif choice == '3':

   print(num1,"*",num2,"=", multiply(num1,num2))

elif choice == '4':

   print(num1,"/",num2,"=", divide(num1,num2))
