Python Classwork: Math Quiz
    Write a Python program named "MathQuiz.py" that randomly chooses
    two integers from one to nine, along with an operator (+ - x /).
    Put those random selections together to display a simple math
    problem to the user, and have the user type an answer to the
    problem.  Then display a random response to the user indicating
    whether the answer is correct or incorrect.  Your program should
    have at least five random responses for correct answers, and at
    least five random responses for incorrect answers.

    Since dividing two integers can result in a decimal answer, all
    answers to division problems should be rounded to one decimal
    place, and when a division problem is presented to the user, he/she
    should be told to round his/her answer to one decimal place.

    Your program does not need to perform any error trapping.  That is,
    you may assume that the user will enter only numerical answers.

    Your program's output should be formatted in a manner similar to
    what is shown below.  You may put all of your code into the main
    area of the program (that is, you are not required to create
    separate functions).  The "randint" function is the only external
    function that your program may import.


    Example Program Run #1
    ----------------------
    Welcome!  Here is your random math problem:

    8 + 5 = ?

    What is the answer?  13

    Good job!


    Example Program Run #2
    ----------------------
    Welcome!  Here is your random math problem:

    2 - 9 = ?

    What is the answer?  -7

    Awesome!


    Example Program Run #3
    ----------------------
    Welcome!  Here is your random math problem:

    6 x 7 = ?

    What is the answer?  42

    Correct!


    Example Program Run #4
    ----------------------
    Welcome!  Here is your random math problem:

    3 / 8 = ?

    What is the answer (rounded to the nearest tenth)?  0.4

    Nice work!


    Example Program Run #5
    ----------------------
    Welcome!  Here is your random math problem:

    8 x 5 = ?

    What is the answer?  13

    Wrong!


    Example Program Run #6
    ----------------------
    Welcome!  Here is your random math problem:

    4 - 1 = ?

    What is the answer?  -3

    I don't think so!


    Example Program Run #7
    ----------------------
    Welcome!  Here is your random math problem:

    5 / 5 = ?

    What is the answer (rounded to the nearest tenth)?  1.0

    Terrific!


    Example Program Run #8
    ----------------------
    Welcome!  Here is your random math problem:

    7 + 2 = ?

    What is the answer?  14

    Nope!
