Hi, I suggest you first simplify the expression you used then restrict the range over which you are plotting initially. Plot3D[(10 E^(2 (x^2 + y^2)) (x - y))/(1 + x^2 + y^2), {x, -1, 1}, {y, -1, 1}] Works fine. I also plotted your original expression on my system OK but it seem to be not very useful to do so. There are an infinite number of ways to get your system and Mathematica to fail, the fun is building up sensible problems that have solutions you can use.
