#GeeklyHub How to Find Determinant of 2x2 Matrix? 3x3 Matrices

Hi there! Welcome to GeeklyEDU by GeeklyHub Math! In this video we are going to learn how to find the determinant of a matrix. Usually, the determinant of a matrix A is denoted as det A, but you can also come across det (A) or |A|, which is pretty much the same thing. With the help of determinant we can later find the inverse of a matrix. Right now, we will cover different ways of how you can calculate the determinant for 2x2, 3x3 and even bigger matrices. Watch our video and with the help of our Math Geek you’ll understand what is the Determinant of a Matrix!
