Simplifying Determinants - Concept

Concept Concept (1)

Finding the determinant of a 3x3 square matrix or a larger square matrix can involve a lot of computation. To reduce the amount of computation, we can use methods for simplifying determinants. These methods for simplifying determinants involve using row or column operations to change some entries of the matrix to zeros.
