<p><tt>Matematical Built-Ins for CWM/Llyn using Strings<br>
<br>
Allows CWM to do addition, multiplication, subtraction, division, <br>
remainders, negation, exponentiation, count the members in a DAML <br>
list, and do the normal truth checking functions, only sub classed <br>
for numeric values.<br>
<br>
All values are represented by string types (untyped literals in RDF).<br>
See math (no s) for versions using numeric types.<br>
