Question

create a program that asks user math questions and keeps track of answers...

Python

1. Allow the user to decide whether or not to keep playing after each math challenge.

2. Ensure the user’s answer to each math problem is greater than or equal to zero.

3. Keep track of how many math problems have been asked and how many have been answered correctly.

4. When finished, inform the user how they did by displaying the total number of math problems, the number they answered correctly, and their percent correct.

Provide meaningful comments
