A sincere question
Thank you for subscribing to my videos, I really appreciate you being apart of my effort to spread math education. I am in the works of creating some new math videos, ones that are edited and longer in length. I want to put them in an app. Before I do this I would like some advice from the people that have viewed my videos.
Do you think the edited videos are too long for an app? What can I do to make my edited and unedited videos better? I am also in the works of creating my website, www.freemathvideos.com. What features would you like to see in a math help website? Currently I plan to just have videos posted. Soon that website will have all of my videos available. Thank you again for watching, and I appreciate any feedback you can give me. You can PM anytime with your thoughts.
Thanks,
Brian McLogan
