# MAFS.912.N-VM.3.10

Understand that the zero and identity matrices play a role in matrix addition and multiplication similar to the role of 0 and 1 in the real numbers. The determinant of a square matrix is nonzero if and only if the matrix has a multiplicative inverse.

Matrices:

This resource is a PowerPoint presentation and a form for guided note taking to be used while viewing the presentation about Matrix Operations. It begins by defining matrices and identifying types of matrices. It then goes into how to add, subtract, and multiply matrices, including how to use scalar multiplication. The final portion deals with finding the determinants of 2x2 and 3x3 matrices and Inverse Matrices.
