Sigh. [psf 10.1]  You have a problem with basic arithmetic, not PHP.  Why 
are you asking in a PHP newsgroup (other than to troll here)?  *At least* 
you should have the decency to ask in a *math* newsgroup (where people will 
tell you, iff they do not ignore you, that you learn these things in 
highschool – or its national equivalent).

Please read <http://www.catb.org/~esr/faqs/smart-questions.html> before you
