break

num2 = float(input("Enter the second number: "))

if choice == "Add":

num1 += + num2

print("The subtotal is: " + str(num1))

elif choice == "Subtract":

num1 -= num2

print("The subtotal is: " + str(num1))

elif choice == "Multiply":

num1 *= num2

print("The subtotal is: " + str(num1))

elif choice == "Divide":

num1 /= num2

print("The subtotal is: " + str(num1))

print("The final result is: " + str(num1))

Explanation:

Ask the user for the first number

Create a while loop that iterates until specified condition occurs inside the loop
