Section Numbering

[iamaman]

I am currently writing a math report and I need to know which
documentclass and which commands to use such that when I type in the
\chapter or \section command, I get a label number of the form "x." and
not "0.x". My problem is that I have been using the report document
class and when I use the section command as my highest, I get something
of the form "o.x" which I dont want as my highest, and when I use
\chapter as my highest, it writes "Chapter x" above my heading which I
don't want. How can I alleviate this problem, like use \chapter w/out
latex inserting a "chapter x" above my heading? Thanks
