Teacher Training Inteview

I was asked:
1) Who invented zero? [Would a Platonist ask "Who discovered zero?"] 
2) Why is zero important?
3) What is a placeholder?
4) What is calculus?
5) A cube is turned so that a corner is vertically above the opposite corner. It is then lowered into some water. In what order do the vertices enter the water?

1) no one.
2) Because it makes a great synonym for "loser".
3) something that holds a place.
4) a small stone.
5) the lowest ones go in first.
Really, what was hard about that?

Yet I almost always agree with myself and I still haven't been conceived as a spammer...

Look at the person agreeing with both Icarus and I. TB, you really do put double meanings into every opportunity. - Reference to other discussion about this.

You can only believe i what you can prove, and since you have nothing proven to cmpare to, you can believe in nothing.
I have ~50 posts to hack a "R" into a "D". Which one?

1,2,3,4--> are these trick question or just meant for fun 
5-->
it was fun to image the experiment.
first the lowest vertex.
then the three 'dry vertices' that can be reached first from the lowest vertex by just walking along the edge.
then the other three 'dry vertices' except the top one.
then the top vertex.

I doubt that the teacher training interviewers were asking them for fun, but we were having fun with them.
If you want something more serious:
1) Earliest known references to zero were found in the Indus valley. But I am a Platonist in so far as I reject the idea that they "invented" zero. I would say that they may have first discovered it. There is reason to believe the Meso-american indians actually had the concept earlier, but the earliest definitive evidence we have is much later.
2) As a mathematician, I could spend all day answering this one. Suffice it to say that the real numbers would not be complete without zero. 
3) The "fun" answer here is also the correct one. A placeholder is a symbol that you put in an expression to represent a value that you do not know, or is not yet set. Most commonly, we use letters as the symbols for placeholders, and we call them "variables".
4) A "calculus" was a small stone used for voting in ancient times. In modern times it is used for the study of limiting behavior of functions.
5) As you said.
