Section 8-5: Cramer's Rule
Ohio Learning Standard(s): N-VM-10
I CAN: 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.

Chapter Eight Review
Ohio Learning Standard(s): N-VM-6, N-VM-7, N-VM-8, N-VM-9, N-VM-10
I CAN: Use matrices to represent and manipulate data, e.g., to represent payoffs or incidence relationships in a network; Multiply matrices by scalars to produce new matrices, e.g., as when all of the payoffs in a game are doubled.; Add, subtract, and multiply matrices of appropriate dimensions; Understand that, unlike multiplication of numbers, matrix multiplication for square matrices is not a commutative operation, but still satisfies the associative and distributive properties; 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.
