Hi everyone,(adsbygoogle = window.adsbygoogle || []).push({});

I am teaching myself Linear Algebra and I am confused with the terminology used in the subject.

I am studying Linear Algebra based on Anton's. In the textbook, an augmented matrix in REF needs to have the first nonzero number in a given row to be 1. However, in other textbooks, the first nonzero number in a given row can be any number.

Which is right? It is based solely on preference?

Thanks :)
