I've taken two upper division courses in linear algebra, and yet a trivial problem has arisen that I am having trouble answering! haha(adsbygoogle = window.adsbygoogle || []).push({});

Let A be the matrix:

[1 2 0 3]

[0 0 0 0]

[0 0 1 2]

Is A in RREF? I say yes, however, the majority of students whose papers I am grading say no. If they are correct, what is the reason?

TIA,

Ryan
