Here is a quiz that asks students multi-choice math questions.
Your task is to expand the quiz to include 8 questions.
You may edit the existing code however you wish.

#Tasks
#1)Adapt the quiz to include 8 math questions
#2)Adapt the quiz to give better feedback if the user get a question wrong
#3)Print a unique message if they get them all correct
#4)For a more complete program, ask the user for their name and print out a final report with a total score of correct/incorrect

Extension:
#E1)Accept the user inputting the numerical value in addition to the multi-choice

#Challenge
#C1)Use functions to remove the excess use of if statements
#C2)Keep track of incorrect answers and the end
#C3)Ask the user if they want to resit the test only with questions they got wrong
#C4)Randomise the order of questions
