% To use this file, please put it in the same directory as your TeX file
% (or some other place where TeX will find it),
% add the 11pt option
% \documentclass[11pt]{article}
% to get 11 point type,
% add the line
% \usepackage{Bridges_LaTeX_Style} to your preamble to load this package,
% and add
% \thispagestyle{empty}
% after \maketitle to remove page numbers on the first page.
%
%% LaTeX indents each paragraph (except the first in each section)
% and does not leave space between paragraphs.
% If you prefer to not indent and leave a line between each paragraph,
% then add the line \paragraphspace to your preamble.

\def\paragraphspace{%
 \setlength{\parindent}{0in}
 \setlength{\parskip}{10pt plus 1pt minus 1pt}
}

% To get 2.5cm margins on all pages.
\usepackage[margin=2.5cm,noheadfoot]{geometry}

% Remove page numbers.
\pagestyle{empty}

% Use Times Roman font.
\renewcommand{\rmdefault}{ptm}

% Use Times Roman font for mathematics.
\usepackage{mathptmx}

% LaTeX adds space before the title and uses 17 point non bold font.
% I've removed space to make the top margin 3 cm on the first page
% and changed the text to 16 point bold.
% The author's name and address is set in 12 point by default.
