Just a note to say THANK YOU.... I am big fan of your Channel, I recently went back to Varsity for my 2nd qualification, BSc in Applied Mathematics, after years with out doing mathematics you made the transition so much easier for me. In Africa we got a word "UBUNTU" you're really personified that. Keep up the good work!

Professor RobBob, thank you for an awesome Introduction to Inequalities and the Classic Number Line in basic Algebra. Inequalities and the Number Line are important tools in Science and Applied Engineering. Inequalities can be used to analyze many problems in real life.

Just found your videos a few days ago and i have a big feeling they will be aiding me in passing trig. Also glad to see that you're going back to the basics as well. I intend to possibly become a math teacher in the future and i'd like to either show them your videos or at the very least use your videos to develop a similar teaching style. I like the idea of teaching the fast learners and then focusing on those that need more in-depth help and with you having to be aware of the time for videos, you tend to lean towards a very fast and pinpoint method. I will also be consulting your videos for all my math classes from here on out that apply. Just wanted to let you know you're a big help.
