My pure math-ist teachers suggests that 0o  is 1. I'm not so sure. In fact the whole thing has become a wee bit of an issue to me and my maths teachers. Why is -2-2 undefined? What am I missing? Despite us saying that we wouldn't use computers each and every one of us did.

Where we worked, well our computers, we found that negative numbers to negative powers were undefined. Umm? Our computers did see this.I was worried because I didn't

So I did a wee bit of work on functions of 2 variables. They seem to define a surface, discontinuous where?  And if they are discontinuous what does that mean for us other functions? You know the D2 ones?

My applied math-ist teachers don't like me playing fast and loose with differential equations, although everyone agrees that what  got out was right. And while it [my solution] has some odd things about it, it was agreed that I managed to differentiate xx.

Well of course I was piqued, but found -2-2 to be -0.02!

No . . . don't say . . . that's not what you meant is it!
