187 – Handout

April 7, 2010

If you need today’s handout on the pigeonhole principle and g.c.d.s, let me know and I’ll bring extra copies to lecture. 

The exercises in the handout are extra-credit. All extra-credit problems, other than the two due this Friday, are due the last day of lecture. (I may change this date, if need be, but let’s try it for now.)
