Jan 01, 2019 · If we multiply matrix A by the inverse of matrix A, we will get the identity matrix, I. The concept of solving systems using matrices is similar to the concept of solving simple equations. For example, to solve 7x = 14, we multiply both sides by the same number. We find the "inverse" of `7`, which is `1/7`.

While the layout of most TI-83/84 models are basically the same, of the things that can be different, one of those is the location of the Matrix key. For most models, the Matrix menu is found by clicking on and, but on some models Matrixis its own key.
