Homework # 2,     Due BEFORE class on Friday, January 21


2.1 parts a and e; 2.3 c, d; 2.5 c, e; 2.7 a; 2.8 b; 2.10 a


Skip all portions referring to "octal".  Note that the answers
to all of these can be found at ddpp.com (so I'll have to use
a quiz to determine if you _really_ know how to do them...)
