### General Math Resources

Note: the internet can in fact do your homework for you in many cases. So can your friends, your mother, and your tutor. That’s not the point. Study (and drink) responsibly.

**Study Math by Speaking It****Tips on Doing Homework****Tips on Reading your Textbook**- Dr. Math – Question answer service (by ‘Math Doctors’). Use the search box first; there’s a 99% chance someone has asked your question before.
- Mathematics at StackExchange – Question answer service (by the ‘hive mind’). Use the search box first; there’s a 98% chance someone has asked your question before.
- Math Forum Digital Library – Catalogue of web resources.

### CU Resources

- The Undergraduate Mathematics Resource Center is in Math 175 (first floor of math building), and is open M-Th 9-5 and F 9-2. Although tutors no longer serve this course, an area has been set up where you can meet your peers to work together.
- A tutor list is available.
