Math in BASIC is relatively straghtforward.  In most cases of simple (+ - * 
/ and ^) math, the BASIC line reads just as you would write on paper.
BASIC is also a fairly easy language to learn and use.  Unfortunately, once 
you really know it, it ruins you for "more advanced" programming langauges 
(C and all its variants, java, etc).  cest la vie

I'd be happy to lend a hand with decoding since I have lots of time this 
week....  But it looks like others may have supplied more user-friendly 
sources.
