[sdiy] SDIY MATH GOALS--need real help!

[cheater cheater]

Dan,
get all the used books you can get your hands on.
People throw away old books because they're 'outdated' all the time.
Hint: the mathematics you need haven't changed in the last 50 years,
and books that are 100 years old are still up to date (but not as
complete)

Make no mistake, cracking is only 1 mm away from mathematics.
