## Math 20B Homework

### Updated 9/21/21

We will have two different kinds of homework assignments in this class: *online homework* (which will be graded) and "paper-and-pen" *textbook homework* (which will not be graded).

## Online Homework

### Online homework (graded) will be done using Achieve via Canvas.

## Textbook Homework

### These assignments will not be turned in and will be not graded; however, exam and quiz questions are often based on textbook homework problems, so understanding the solutions to these problems should help you perform better on the exams and quizzes. (Also, if you seek help from the instructor or TAs, they may do these problems instead of the online problems.)

### Note:
- The "due dates" given are the same as the dates when the corresponding Achieve assignments are due.
- This list is subject to revision during the term. Please check regularly for updates.
