More Matrices...

Well, we have another day of matrices. Actually today was more easy to learn. One new thing we learned today was that equal matrices are matrices with the same dimension and elements. Pretty easy right? But nooooooo. After going through that, we have to find the determinant. What we do is we add the matrices together then we take the matrix and then we mulitply diagonally and then subtract the two products and we get the deterimant. Wait, what?
