The inverse of a matrix A is A⁻¹, just as the inverse of 2 is ½. We can solve equations by multiplying through by inverses; it's similar with matrices.

Determinant of a Matrix: In order to determine whether or not we can find the inverse of a matrix, we need to compute its determinant. This is a single number, and its formula is different depending on the size of the matrix. If this determinant is not zero, the matrix is invertible....
