14 years later and its still useful. Thanks man!

I really can't thank you enough. I'm in Pre-calculus about the finish my AA degree and I didn't think I had a chance to pass. With your help, I'm flying through the problems!! Thank you.

Almost 10 years later of posting this video you just made my night doing math homework easier !!!

[legomomboys]

Finally a clear explanation! I just did my homework that I had been struggling for over a week, in less than a half hour!!! Thank you so much!

[hypnosstratagem]

Very clear instructions. Thank you so much. This is going to be very helpful in my linear algebra course!

Well, if you are being tested on how to do it by hand, I do have videos that show that as well for both a 2x2 and 3x3. It really depends on what your instructor is testing you on.

thank you so much! I would never have understood my assignment without you!

Thank you for putting this up, straight to the point, needed help specifically for 3x3 matrices for finding the "change of coordinates" matrix. Thank you again.

[wondrousinquiry]

oh gosh thanks so much...my textbook didn't teach us this. i almost had a heart attack when i had a homework problem asking for the inverse of a 3x3. thank you again!

[TheTimmay]

Thank you so much dude! This makes it way easier!

[charliesalem]

Most helpful video in a while thank you!

[crosstolliver]

Thanks this helped a lot. It was very simple and explanatory.

Here in 2022 with my graphing calculator Ti-84 plus CE. Thanks for your help!!

In order of a matrix to have an inverse it must be a square matrix and its determinant can not be zero.
