Aʙᴏᴜᴛ Tʜɪs Vɪᴅᴇᴏ – This video looks at finding and working with the determinant and inverse of both a 2 x 2 and a 3 x 3 matrix. We discover how to easily find the determinant and also use it to display the inverse in a different form than given by the calculator. We also confirm a matrix multiplied by its inverse gives the identity matrix.

Aʙᴏᴜᴛ Tʜɪs Vɪᴅᴇᴏ – This video looks at a variety of types of matrix multiplication using the Casio Classwiz fx-991EX Calculator. We start with scalar multiplication and then multiply some of the matrices together. We also square matrices and look at an example where matrix multiplication is not possible. We also show evidence of matrix multiplication is not commutative, giving different products dependent on the order of multiplication.
