Determinant of a Matrix - How to Find (2x2 & 3x3)

[@lisapardee8234]

I'm a special ed teacher teaching Algebra 2. Your videos help me every single day! I told my students about you too. You make everything SO easy to understand.

Thank you for explaining it so clearly, and especially thank you for that shortcut for a 3x3!

Why did you write +3[-2 2
5 2] when others are minus?

[@indianinstituteoftechnolog5290]

Please give something for 4 x 4

[@ososracing4037]

Does the first method of finding the determinant works on any NxM matrix?

[@MariosMathTutoring]

The method shown in this video is just for 2x2 matrices...there are other techniques for 3x3 etc.

[@YewrMan]

Nicely explained Mario. Cheers.

[@MariosMathTutoring]

Glad you liked the video Tony!
