What is the determinant of a matrix in math?
Answer
Matrices can often be confusing to many students who first come across the concept. The determinant is helpful to use when finding matrices and answers, but can be tricky.
When given a matrix, for example a 2x2 matrix, the process involves finding the cross products across the diagonals and subtracting the difference. This will give you a number which can then be used for many different verification and operation purposes, such as finding unknown values, finding inverses, and verifying the matrix as singular or not.
