    My number is less than 200.
    My number is even.

    I don't think 75 is an even number!
    Here's a question my high school math teacher asked us:

    You have 23 cubes of sugar. How can you put them all in two cups of coffee so that each cup of coffee has an odd number of sugar cubes in it (you can't break the cubes, although that wouldn't help).

    After much deliberation and frustration by the class, she gave us the answer. She said, "Put 22 cubes in one cup and one cube in the other."

    When we all protested that 22 is an even number, she calmly replied, "But isn't 22 an odd number of sugar cubes to put in a cup of coffee?"

    I would have punched that teacher directly in the ovaries if she gave me a BS math puzzle/answer like that.

    Typical test issue in my life, transcribed the wrong answer from my scratch sheet.

    After hemming and hawing over the criteria - I opted for the easiest solution. 2 In mathematics, a prime number (or a prime) is a natural number which has exactly two distinct natural number divisors: 1 and itself. In this example - 1 & 2.
