I have the following equation

begin{equation}

    Ep = (Required Personality Level of Each Resource - Assigned Personality 

    Level of each Resources) times (datextsubscript{i})

end{equation}

but it is too large as is.
How should I write it so it can fit nicely on the page?

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):

documentclass{article}

begin{document}



begin{equation}

  Ep = P_l times da_i,

end{equation}

%

where $P_l =$ Required Personality Level of Each Resource-Assigned Personality Level of all Resources



end{document}

break your long text into two lines:

documentclass{article}



begin{document}

begin{equation}

    Ep = left(begin{tabular}{l}

                Required Personality Level of Each Resource-\

                Assigned Personality Level of each Resources

                end{tabular}right)

        times (da_{i})

end{equation}

end{document}

no other option is available?

Another option is to use resizebox. This will automatically shrink the size of the equation to make it fit. Ofcourse, for very long equation, the font will become too small to read without zooming in. But it is an option and you asked for another option. The accepted answer method would be my first choice.

documentclass[12pt]{article}



usepackage{graphicx}

usepackage{amsmath}



begin{document}



begin{equation}

    resizebox{textwidth}{!}

     {%

        $Ep = (text{Required Personality Level of Each Resource - Assigned Personality Level of each Resources})

                  times (datextsubscript{i})$%      

     }

end{equation}



end{document}

Hope you are looking for autobreak option in display math? If yes, refer the below tag:

documentclass{book}

usepackage{amsmath}

usepackage{autobreak}



begin{document}



allowdisplaybreaks



begin{align}

begin{autobreak}

    Ep = 

(Required Personality Level of Each Resource - Assigned Personality 

    Level of each Resources) 

times (datextsubscript{i})

end{autobreak}

end{align}



end{document}

By using amsmath I can think of two more options: you can use

• 
  multiline (justified multiline formula)


• 
  split (allows to align about certain character without bulky tabular construction)

environments. Note that text in math equations is typically upright; I also adapted subscript notation to use in math environment:

documentclass{article}

usepackage{amsmath}



begin{document}



begin{multline}

    Ep = (text{Required Personality Level of Each Resource}\

    - text{Assigned Personality Level of each Resources}) \

    times (da_mathrm{i})

end{multline}



begin{equation}

    begin{split}

        Ep &= (text{Required Personality Level of Each Resource}\

        &- text{Assigned Personality Level of each Resources}) \

        &times (da_mathrm{i})

    end{split}

end{equation}
