# 15-344/Homework Assignment 3

This assignment is due at the tutorials on Thursday October 15. Here and everywhere, **neatness counts!!** You may be brilliant and you may mean just the right things, but if the teaching assistants will be having hard time deciphering your work they will give up and assume it is wrong.

**Add** your name to the Class Photo page! (This of course is not mandatory, but it is fun).

**Reread** sections 2.2-2.4 of our textbook. Remember that reading math isn't like reading a novel! If you read a novel and miss a few details most likely you'll still understand the novel. But if you miss a few details in a math text, often you'll miss everything that follows. So reading math takes reading and rereading and rerereading and a lot of thought about what you've read. Also, **preread** chapter 3, just to get a feel for the future.

**Solve** problems __1__, 9, 19, 20, __21__, and 22 in section 2.2, problems 1abcdfghijklnoqr, __1emp__, __10__, and 12 in section 2.3, and problems 1, 3, __5__, and __9__ in section 2.4, but submit only your solutions of the underlined problems.
