One of my students really struggles with ERO's. I taught him how to calculate the inverse using determinants and cofactors, but I'm unsure how to teach him reduced row echelon form in another way besides ERO's. My question -- Is there any way to reduce a matrix to row echelon form without using ERO's?

OpenStudy (anonymous):

well teach him the very basics first. Why ERO's work. Teach him in normal non matrix math first so he can draw the link.

@A.Avinash_Goutham elementary row operations. @timo86m That wasn't my question

OpenStudy (anonymous):

OpenStudy (anonymous):

but u shd use ero's sry........

OpenStudy (anonymous):

Well if you just wanna know how to calculate it then that is all. If you understand the more basic first you can get creative. I guess lol.

whats the application of ERO's? just beacuse its some concept,,its not necessary that he should know.. co-factor method is the easiest and quite effective,,i would have avoided ERO in this case..
