Okay so I'm a first year engineering student and I'm taking linear algebra.(adsbygoogle = window.adsbygoogle || []).push({});

I understand how to take determinants of nxn matrices, and I know how to do co-factor expansion. But I still don't understandwhat a determinant is.

I don't like learning algorithms on how to do certain things in math without knowing why it works. I hope someone can answer the "Why?" question for me.

To keep is simple as possible: What the hell is a determinant?
