Something that occurred as kind of a surprise - an example problem in our
text involved the income figures for Oprah, Seinfeld, and Simon Cowell.
Given relations between their incomes, you have to find the specific
values.  Kind of a silly, typical, schoolish text book problem.

So I entered the following in SAGE:

Cowell = x
> Seinfeld = Cowell + 15
> Oprah = Cowell + 215

(figures represent millions)

When you evaluate this, SAGE produces the more typical algebra equation:

was going on.  It was a pleasant surprise for me, as I hadn't intended for
that to be the point, but of course!, you can organize the information from
a word problem in this kind of intuitive pseudo-codish way, and SAGE will
translate your expressions into standard algebra.

So that was fun.
