This blog is a collection of my precalculus lessons produced between 2010 and 2014. The original math websites relied extensively on Adobe Flash, which meant that as the browser plug-in was eradicated from the web, my websites became unusable. The constant security warnings "This page contains Adobe Flash and may not be secure" really drove away visitors to the websites, and usage was dwindling. Furthermore, as schools were rapidly removing Flash from their computers, Flash-based projects were - for all intents and purposes - depreciated to the digital garbage heap of educational history.  By 2014, it was becoming clear that there was no future for Flash-based development, so I returned to teaching after finishing the Math 10C and Math 30-1 websites. There is no content for Math 20-1. Finally, in 2018 (shortly before Flash was fully banned from browsers),  I pulled the websites off the web rather than face the daunting task of redoing years of work without Flash. While this ...
