My regression equation is not done yet, but the look of it is a but odd. Can someone help me with the spacing?

\begin{document}
OLS Regression is used to estimate the following equations:
${\textrm{CEO Salary}}={\beta}_0 +{\beta}_1 return$ +${\beta}_2 bonus$+${\beta}_2 stock awards$+${\beta}_2 option awards$+
\par${\beta}_2 other compensation$
\end{document}
@DavidCarlisle this is resulting in errors: what am I doing wrong?
{\textrm{CEO Salary}}={\beta}_0 +{\beta}_1 \mathrm{return} +{\beta}_2 \mathrm{bonus}+{\beta}_3 \mathrm{stock awards}+{\beta}_4 \mathrm{option awards}+
\par${\beta}_5 \mathrm{other compensation}+{\beta}_6 \mathrm{age}+{\beta}_7 \mathrm{age sq}+{\beta}_8 \mathrm{male}+{\beta}_9 \mathrm{industry}+{\beta}_10 Volume$


\mathrm{return}etc and don't do$ +$which is forcing the + not to be part of the math expression, – David Carlisle May 02 '18 at 15:57_{1234567}if you know what you are doing you can sometimes omit the braces without it going wrong but it is a bad idea to do that, even when it works. – David Carlisle May 02 '18 at 16:25{and}). – gvgramazio May 02 '18 at 16:27
