The Limits of Mathematics---Tutorial Version http://arxiv.org/abs/chao-dyn/9509010v1 http://arxiv.org/abs/chao-dyn/9509010v1 Previously in this LISP code only one-character identifiers were allowed, and arithmetic had to be programmed out. Now identifiers can be many characters long, and arithmetic with arbitrarily large unsigned decimal integers is built in. This and many other changes in the software have made this material much easier to understand and to use.
