  • I'm live in Austin, too! I might just drop by ACC to for tutoring in the flesh! ;D your videos are splendid

  • @theredgear12 good luck with acc, i have not been there for years now :) only a brief stop at that place for me!

  • my teacher told us that your are not supposed to subtract or divide when solving these, but you can multiply by fractions. Why can we not divide and why did you divide by five?

  • @macoglesby it could be the desire to avoid fractions, which kill many people

  • @patrickJMT I think he is thinking you shouldn't divide matrices.

  • @TheExtinctSpecie well, but you can subtract matrices, so i am not sure what he means.

  • @philbot01 ha, my long lost twin

  • These are easy, its just that its a lot of little steps and one wrong step means that everything is wrong

  • Math is so beautiful.

  • thnx for these simple yet very helpful tutorial...

  • @patrickJMT and please excuse my dear aunt sally, jk, my grammar -_-

  • @patrickJMT I actually go to UT :) but thanks anyway! so you do YouTube math videos for a living now...?

  • @TheExtinctSpecie well but you can multiply them. So if you multiply a matrix with a fraction then you have divided it. There's nothing wrong with that.What you cannot divide is a matrix with a matrix (sorry my math english is not very good,I hope you understood)

  • thank you!

    you got nice hand btw :))))

  • can I use this gauss jordan system with other matrix than 3x3 dimensions but still square?

  • @tRGodzApostle

    No doubt man. I just finished calc 2, and it was ten times easier than this horse shit
