equations
I have the following equation
\begin{equation}
Ep = (Required Personality Level of Each Resource - Assigned Personality
Level of each Resources) \times (da\textsubscript{i})
\end{equation}
but it is too large as is.
How should I write it so it can fit nicely on the page?
You can use the multicol package. Either you end a multicol environment before the equation and restart it after, or you define an environment like this:
\documentclass[parskip]{scrartcl}
\usepackage[margin=15mm]{geometry}
\usepackage{multicol}
\usepackage{lipsum}
\pagestyle{empty}
\newcommand{\OneColEqu}[1]{%
\end{multicols}%
\begin{equation}%
#1
\end{equation}%
\begin{multicols}{2}%
}
\begin{document}
\begin{multicols}{2}
\lipsum[1]
\end{multicols}
\begin{equation}
\int\limits_{x=0}^{x=5}(x^2+2x-3) dx = \left[ \frac{1}{3}x^3+x^2-3x+C \right]^{x=5}_{x=0} = \frac{125}{3}+25-15+C-C= \frac{155}{3}
\end{equation}
\begin{multicols}{2}
\lipsum[2]
\OneColEqu{\int\limits_{x=0}^{x=5}(x^2+2x-3) dx = \left[ \frac{1}{3}x^3+x^2-3x+C \right]^{x=5}_{x=0} = \frac{125}{3}+25-15+C-C= \frac{155}{3}}
\lipsum[3]
\end{multicols}
\end{document}
Both approches yield the same, but the own command probably is more convineant:
Edit 1: Putting the equation always on the bottom can be achieved by defining a custom float with the float package:
\documentclass[parskip]{scrartcl}
\usepackage[margin=15mm]{geometry}
\usepackage{multicol}
\usepackage{float}
\usepackage{lipsum}
\pagestyle{empty}
\floatstyle{plain}
\newfloat{twocolequfloat}{b}{zzz}
\floatname{twocolequfloat}{Equation}
\newcommand{\OneColEqu}[1]{%
\end{multicols}%
\begin{twocolequfloat}%
\ensuremath{\hfill #1 \hfill}%
\end{twocolequfloat}%
\begin{multicols}{2}%
}
\begin{document}
\begin{multicols}{2}
\lipsum[1-3]
\OneColEqu{\int\limits_{x=0}^{x=5}(x^2+2x-3) dx = \left[ \frac{1}{3}x^3+x^2-3x+C \right]^{x=5}_{x=0} = \frac{125}{3}+25-15+C-C= \frac{155}{3}}
\lipsum[3-7]
\OneColEqu{\int\limits_{x=0}^{x=5}(x^2+2x-3) dx = \left[ \frac{1}{3}x^3+x^2-3x+C \right]^{x=5}_{x=0} = \frac{125}{3}+25-15+C-C= \frac{155}{3}}
\lipsum[8-14]
\OneColEqu{\int\limits_{x=0}^{x=5}(x^2+2x-3) dx = \left[ \frac{1}{3}x^3+x^2-3x+C \right]^{x=5}_{x=0} = \frac{125}{3}+25-15+C-C= \frac{155}{3}}
\lipsum[15]
\end{multicols}
\end{document}
\floatstyle{plain} same stlye as LaTex (no rules around the float)\newfloat{twocolequfloat}{b}{zzz} new float twocolequfloat, which is always aligned bottom, for posiible use in listof... or something the file .zzz will be written\floatname{twocolequfloat}{Equation} name displaed e.g. if you use labelsThen we use this environment for our math:
\begin{twocolequfloat}% begin environment\ensuremath{\hfill #1 \hfill}% make sure formula set in mathmode, use \hfill to center it\end{twocolequfloat}% end environmentHowever, the formula will always be set to the bottom of the page. If your text ends after 20% of the page, the formula will be far away.
I advise against using \Large equations, particularly if this creates too wide an object.
However, here's a possible solution that doesn't mess up the vertical spacing:
\documentclass[12pt]{article}
\usepackage{amsmath}
\usepackage{lipsum}
\begin{document}
\lipsum*[2]
\[
\noindent\begin{minipage}{\textwidth}
\Large
\[
\hidewidth
\sum_{t_1=1}^{n}\binom{n}{t_1}+
\sum_{t_1=1}^{n-1}\sum_{t_2=1}^{n-1}\binom{n}{t_1,t_2}+\dots+
\sum_{t_1=1}^{1}\sum_{t_2=1}^{1}\cdots\sum_{t_n=1}^{1}
\binom{n}{t_1,t_2, \dots, t_n}
\hidewidth
\]
\end{minipage}
\]
\lipsum[3]
\end{document}

Mathematical symbols where created to represent the meaning of longer descriptive words in a short form for easy inclusion in complex formulas with possible repetition. I would choose a suitable symbol/character to represent that long sentence like this (choose your own descriptive symbol):
