I wrote you a couple of years ago, telling you that when I hit 65, I can take math for free at the community college. You said for me to go for it. Well, as of next tuesday I will be 68 but still have not gone back. I am old and these summers are killing me. What I may do, is take your tutorial classes that you offer and learn what I could not learn on the computer when I was 60. I know, I know, why bother right ? Well, I have always been bad at math and would love to just for my own peace of mind, be better at it. Thank you Mr. Whitt.

Thanks so much Babilon Kay!
Psyched to see you back with another video! I'm an adult relearning math as a hobby. I haven't gotten to trig yet, but I upvoted this (as I'm a big fan of your past work) and saved it for when I get there.
Thank you , Thank you.

@@FortBendTutoring My Pleasure. You have no idea how much you helped me back 4 years ago. I have forgotten so much i have to go back to grade school for some of this. I will be needing you soon.
Mr. Whit, Mr. Whit, Mr. Whit! It's good to see your handsome face. Pretty please with cheese do a few problems with pre-algebra, specifically NC 8th grade, with your handsome face and smooth tone. My students would absolutely love it. I teach math, but I like to assign them a video every now and then. They don't identify with Sal Khan always. Just sayin'. Thanks.
If you would lose the stupid music in the beginning, you would get a lot more watch time and subs. Check your analytics, I bet you get a dramatic drop in viewer retention during the music intro.

Hey Raymond! I just checked and the analytics show that this video held retention at the beginning of the video longer than my average video. I will note that you think my intro music is stupid.

@@FortBendTutoring - If that's from new viewers that's great. If just from subs that get notified, not so much. I know I was a bit harsh, but it took me several months to finally watch one of your videos because I could never watch past the intro. Once I was able to finish one of your videos I found you to be a very good teacher. You've been posting videos for ten years, but still haven't figured out KZread. You should have over a thousand videos posted by now with ten times more subs and 5 to 10 million in the bank just from ad revenue. But if this is just a hobby for you, I guess it doesn't matter. Peace Out.
