print("Enter 'subtract' to subtract two numbers")
print("Enter 'multiply' to multiply two numbers")
print("Enter 'divide' to divide two numbers")
print("Enter 'quit' to end the program")
user_input = input(": ")

if user_input == "quit":
break

elif user_input == "add":
num1 = float(input("Enter a number: "))
num2 = float(input("Enter another number: "))
result = str(num1 + num2)
print("The answer is " + result)

elif user_input == "subtract":
num1 = float(input("Enter a number: "))
num2 = float(input("Enter another number: "))
result = str(num1 - num2)
print("The answer is " + result)

elif user_input == "multiply":
num1 = float(input("Enter a number: "))
num2 = float(input("Enter another number: "))
result = str(num1 + num2)
print("The answer is " * result)

elif user_input == "divide":
num1 = float(input("Enter a number: "))
num2 = float(input("Enter another number: "))
result = str(num1 / num2)
print("The answer is " + result)

Answer 1

nothing is wrong, it is an infinite loop, so all the inputs should be given at the same time..
and at the end you have to provide quit.. to exit the program
ex:

add
5
4
multiply
6
3
quit

Answer 2
