Submit homework separately from this workbook and staple all pages together. (One staple for the entire submission of all the unit homework)
Start a new module on the front side of a new page and write the module number on the top center of the page.
Answers without supporting work will receive no credit.
Some solutions are given in the solutions manual.
You may work with classmates but do your own work
