I suspect they'll soon confuse, er, I mean, disabuse you of that idea. You can't derive negative numbers that way, for example, or a lot of the other weird types of numbers that we have defined (I'm not going to get into the whole discovered/invented argument), or in fact, most of mathematics, it seems to me. </span></div><div><br></div><div><span>Counting things is probably an obscure, tiny and trivial corner of maths.</span></div><div><br></div><div><span>--</span></div><span>Ben</span>
