Welcome to my Website
Thank you to everyone at Victor Valley College for the warm reception, and for your openness to some different ideas about mathematics. I hope all of you will give yourselves permission to use five minutes of any class session to share the things you find interesting in, and around, mathematics.
You can download the slides from any of my presentations by clicking on the Presentations button. If you would like to see some of my blog posts, just click on the Blog button.
I started my own publishing company, XYZ Textbooks, in 2010 with the goal of lowering the price students pay for developmental mathematics textbooks (link below).
Also, we have redesigned our sister site, MathTV.com, where we have thousands of free videos covering topics from basic mathematics through calculus.
And finally, I am happy to report that my YouTube channel has passed the 7,000,000 view mark.
I hope you enjoy my site.
