I typed in an array when I was just messing around, and saw that it was in matrix form. It had 3 things underneath it: determinant, inverse, and transpose. What do these mean? Just wondering.
Hi Helper,
There is no super quick answer to this but here are some video units you can watch to learn a little about matrices.
The Khan academy has some really great teaching tools, you maye find these quite interesting. :)
