''' Program make a simple calculator that can add, subtract, multiply and divide using functions '''

# This function adds two numbers
def add(x, y):
return x + y

# This function subtracts two numbers
def subtract(x, y):
return x - y

# This function multiplies two numbers
def multiply(x, y):
return x * y

# This function divides two numbers
def divide(x, y):
return x / y

print("Select operation.")
print("1.Add")
print("2.Subtract")
print("3.Multiply")
print("4.Divide")

# Take input from the user
choice = input("Enter choice(1/2/3/4):")

num1 = int(input("Enter first number: "))
num2 = int(input("Enter second number: "))

if choice == '1':
print(num1,"+",num2,"=", add(num1,num2))

elif choice == '2':
print(num1,"-",num2,"=", subtract(num1,num2))

elif choice == '3':
print(num1,"*",num2,"=", multiply(num1,num2))

elif choice == '4':
print(num1,"/",num2,"=", divide(num1,num2))
else:
print("Invalid input")
