If I write the regular expression a followed by a plus, it matches a, aa, aaa, aaaa.

Find f g of x. Or you could interpret this is as f divided by g of x.

Define earth.

Just explain those two words

Rise is the same thing as change over y, and run is the same thing as change over x.

Once we have a grip on semantics, we can introduce optimization, where we replace one program with another or, conceptually, one part of a program with another as long as the whole thing has the same semantics.

Archie lets it die down.

And so there is no limit.

It could be equal to the codomain.

Type checking and semantic analysis.
