I'm using mathematica to do some matrix manipulation of matrices with
symbolic elements. I end up with elements having elements that evaluate
to zero, but instead of zero I get something like 

0.X+0.Y

so my matrices become large with uneeded elements... is there a setting
I can change so it will automatically evaluate these to zero?
