Do #35, but only parts (i) and (ii), on page 139. Disregard the word "field" in part (ii), just do what he asks. Do ## 10,11 on page 130. Also do #35 part (ii) if you haven't before Monday. Do #27 on page 139. Do #35, part (iii) on page 139, and also do ##31,34 on the same page. As a suggestion, you can try ##38,39,40,41,42 on page 146. This is about ring homomorphisms.
