I am currently stuck on the following problem. I have never seen a syntax like this. Could someone explain me what is going on. Why is my determinant equal to four squares (the A matrix, the 0 matrix, the negative identity matrix, and my B matrix). What does the cross dividing them unto four squares mean. How am I supposed to interpret this?
If I read the theorem correctly: It says that the determinant of the dot product between two matrices is equal to the dot product of two matrices.
I know how to calculate a calculate a 2x2 matrix or 3x3, but I find this too theoretical.
Sorry for the confusion, thank you for any answers or tips.
