It does exist. A math lesson

I like it when I can solve complex mathematical stuff during breakfast.

Once, in AP Calc with Mrs. Sagorski, we discussed whether negative zero existed. I don't remember the answer and probably got it and most other questions wrong on the AP test.

If only the question was this:
Negative zero is:
A) Cold
B) Complicated
C) Real
D) All of the above
E) None of the above.

So tricky.

Glad that's over.
