  1. Love your math videos, it helped me so much that you can not even imagine. In my opinion it’s even better than YouTube tutorial. I will be recommending your video to my grandkids that both are in their last year of high school. Please add other math videos as like Adding property of equality with Integer. To say that you are an outstanding, unique, and excellent math professor, is an understatement. Thank you very much

  2. I just wanted to say that I was in your Basic Skills 9 course at Victor Valley College and your lectures really helped me get through Math 10. I am thankful that I remembered that you have a website with very informative video lectures to take notes on since I decided to come back here to freshen up on my skills before I take another attempt at Math 42, which I failed the first time since taking this subject as an online course just isn’t recommended. My notes even came out as clear as they did from when I first took this class. I also love the new site layout. It makes everything a little more user friendly. Keep up the good work and I hope that this website can stay online for as long as possible.
