You subtract the corresponding elements to get your result.

This is one of the easier matrix operations. Here is an example:

[a b c]-[g h i] = [a-g, b-h, c-i]

[d e f]. [j k l] ... [d-j,. e-k,. f-l]

Ignore the "."; it's the only way to space things right now.

Since we are subtracting corresponding elements, the matrices must have the same dimensions; the answer must also have the same dimension.
