Of course, we cannot criticise LATEX until we know its full capability. So the first place to go from here is the LATEX User's Guide & Reference Manual. Particularly, the command reference guide in Appendix C of that book is an invaluable source of LATEX information that few can afford to do without. With good knowledge of the LATEX environments and their options (and we've left out many here) one can accomplish a good deal of most typesetting problems. A little imagination (say putting an environment to a slightly non-standard use) can often solve more difficult problems. Lastly, of course, much of raw TEX still sits underneath LATEX and so it is true to say that you can do anything with LATEX—but you may need some divine inspiration from time to time (ask your local TEX guru).
In the next chapter we will look, very briefly, at a number of LATEX commands that we have not yet considered. Nothing exciting on the mathematical front, but there is some other important material (e.g. cross-referencing and page-sizing). For now, let's look at the ``way forward'' with respect to mathematical typesetting.
