I got an error 'break' outside loop

Question

while True:
print("Options:")
print("Enter 'add' to add two numbers")
print("Enter 'subtract' to subtrack two numbers")
print("Enter 'mulitply' to muliply 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)

else :
print("Unknown input")

what's the matter with this.. code?
