Mathematician help required.
Can you help me out? My day job is in hypergeometric differential topology, nothing too exciting. Now my professor has charged me with substituting her to hold a freshmen's lecture. Point is, they aren't even doing normal simple stuff like proofs, series expansions, or matrix diagonalisation. Instead they are using actual numbers, doing mean things like addition to them, to make even more numbers!!
As something that she considers a “simple example”, she has included a walk-through of a soap recipe into the lecture. Like in, real-world things! Gasp. Until now I've believed that soap is something that falls out of a factory. Just to learn that they're handling numbers, and they call it “math” as well – though it appears that it has nothing in common with ordinary mathematics. I'm at a loss. Can someone help me please?
