This course assumes the student has a good grounding in basic school algebra. Students who diligently follow the instructions and examples and work the exercises should have a good grounding for a first course in calculus.
Prof. Bales is beginning the process of updating this site, written in 2000, to modern technology. The site was moved several years ago to http://jwbales.us/precal/ and the site here at http://jwbales.home.mindspring.com/precal/ will soon be shut down. Look for a much improved appearance of the jwbales.us site sometime in the Fall of 2012.
