Thank you! This must have been a lot of hard work, one of the first linear algebra videos that didn't make me fall asleep. Thanks again!

Thank you so much. The book that I am trying to read is was to hard to understand and you make linear algebra very simple and concise.

Excellent video!! Greetings from Argentina

this was amazing. thank you!

Thanks! This makes more sense now
