2. 5 DETERMINANTS AND MULTIPLICATIVE INVERSES OF MATRICES By the end of the section

2. 5 DETERMINANTS AND MULTIPLICATIVE INVERSES OF MATRICES By the end of the section students will evaluate determinants, find inverses of matrices, and set up matrix equations. Students will demonstrate this by creating a foldable.

Didn’t matrices come from systems of equations? When are we going to get to

Didn’t matrices come from systems of equations? When are we going to get to those because I LOVE solving systems of equations! More than Christmas!! •
