Algebra Worksheets 

Use CTRLF to find specific topics. There are class notes from Intermediate algebra at the top of the page. If you print PowerPoint presentations, find, in the
print dialog, where it says it will print "slides" and
change that to "handouts". Then select "2 (or more) slides
per page". This will save paper.
