Write a Python program that acts as a simple math quiz. Your program should: Continuously ask the user a single math question: “What is 7 + 3?”. Allow the user to input their answer. Check if the input is a valid number. If not, print an “Invalid input” message and let them try again. If the input is a valid number, compare it to the correct answer. If the answer is correct, print a “Correct!” message, and the program should then exit. If the answer is incorrect, print an “Incorrect” message and ask the question again. Your program should be able to complete this in 17 lines of code or fewer. However, if you go over, no points will be deducted. You do not need to use functions unless you want to. Sample Run: Plaintext Welcome to the Math Challenge! What is 7 + 3? Your answer: five Invalid input. Please enter a number. What is 7 + 3? Your answer: 9 Incorrect. Try again. What is 7 + 3? Your answer: 10 Correct! Well done!
