Finding the Inverse of a Matrix
Aligned To Common Core Standard:
High School - HSA-REI.C.9
What is the Inverse of a Matrix? They say there is always another side to the story, or there are always two sides to a picture. One concept in mathematics that involves having an inverse in it is the concept of Matrix. Matrices are one of the most powerful tools in mathematics. They are the basic part of mathematics and an important concept used in higher studies and real-life problems. Matrices were discovered to obtain a simple and easy solution for solving the linear equations. But before you go on to finding what the inverse of the matrix is, have a grasp on the basic concept of matrix first. A matrix is a collection and display of numbers. It is an ordered rectangular arrangement of real or complex numbers. On the other hand, what is an inverse of a matrix? The inverse of a matrix is the matrix when multiplied by itself, results in the identity. Suppose A is a matrix which, when multiplied by the same A matrix, results in the identity of that particular matrix. The notation for this inverse matrix is A–1. Here, the important thing to remember is that not all matrices have an inverse. Non-square matrices do not have inverses.

Sorry for the super long explanations here. I just wanted to make sure to be thorough.
