LaTeX Help with an Equation Array

I need help with this equation array.

\begin{align}
\bra{+}\hat{H}\ket{+}&=\frac{1}{2}(\bra{e}+\bra{o})\hat{H}(\ket{e}+\ket{o})\\
&=\frac{1}{2}(\bra{e}\ket{e}E_e+\bra{e}\ket{o}E_o+\bra{o}\ket{e}E_e\\
&+\bra{o}\ket{o}E_o)\\
&=\frac{1}{2}(E_e+E_o).
\end{align}

I just want it to list one equation number, but it lists one for every line. How do I control that?

Also, I can see the unrendered code if I hover over the math, right click, and select ShowMathAs->Tex

Thanks,
