Domain - Vector and Matrix Quantities
Cluster - Perform operations on matrices and use matrices in applications.
[PC.N-VM.C.12] - (+) Work with 2 × 2 matrices as transformations of the plane, and interpret the absolute value of the determinant in terms of area.
[PC.N-VM.C.8] -
(+) Add, subtract, and multiply matrices of appropriate dimensions.
[PC.N-VM.C.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.
