Math 20B Homework

Updated 3/5/26

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.

No homework assignment scores will be dropped at the end of the quarter. However, you will be allowed up to three (3) additional days past the due date to submit each assignment (except the last assignment, which must be completed by the final exam).
Note: Homework may not be submitted after Saturday, March 14 (the day of the final exam).

Textbook Homework

These assignments will not be turned in and will be not graded; however, exam questions are often based on textbook homework problems, so understanding the solutions to these problems should help you perform better on the exams. Note: The "due" dates for these assignments have been set to coincide with the due dates for the online (Achieve) homework.

This list is subject to revision during the term. Please check regularly for updates.
