Having trouble with with if statements being accessed in python 3

I'm writing a test program that's a math game. I'm working on displaying if the user answers a question correctly that it displays 'correct' (in the shell for now), but it never displays correctly even if all the 10 questions are answered correctly. I have tried multiple things such as changing variables back and forth, which has not achieved anything, and added many print statements to see if the if statement was being accessed, which showed only one thing that was not being accessed.
