I am having some difficulty with identity matrices in linear algebra at the moment. I am sure it is fairly simple to solve, but I just cannot follow the logic behind this particular problem.
I need to come up with a matrix B (2x2), such that B =/= I but B2 = I
Since
If I am attempting this correctly, I have to find a number that isn't 1, but if you square it, it equals 1. So I came up with this.

Code:
I = (1 0)
(0 1)

Code:
B = (-1 0)
(0 -1)
