Negative of a Matrix
The negation of a matrix is formed by negating each element of the matrix:
-A = -1A
So, for example:
It will not surprise you that A + (-A) = 0
Each element in the result is the negative of the original, as seen below.

Look at the above fact. Can you think of a way to define matrix subtraction?
