am fairly new to mathematica. simply want to add two 3x3
matrices together(actually, subtract). if they are called
m and p, if i type m-p, mathematica treats the second matrix p as a scalar and subtracts that entire 3x3 matrix p from each entry of m. the help contents do not seem to address this issue!!! there must be a simple way of doing this??

thanks in advance for any help
