About kisker87's channel

The videos you see here have primarily been created to assist my Pre-Calculus and Algebra II students with challenging problems and concepts. I also like to discover ways to do typical math problems on the TI-84 calculator, so there are a growing number of TI-84 tutorials avialable as well.

I'm always up for requests! I absolutely love what YouTube user PatrickJMT has done on his channel and would love to emulate it. The sheer number of videos that he has available for anyone to view is amazing!
