Here is a set

\begin{matrix} 3\,+\,(\,2\,\times\,(\,36\,-\,4\,)\,) & = 67 \\\\ (\,3\,\times\,2\,)\,+\,(\,36\,\times\,4\,) & = 150 \\\\ (\,(\,3\,+\,2\,)\,\times\,36\,)\,-\,4 & = 176 \\\\ 3\,+\,(\,(\,2\,\times\,36\,)\,-\,4\,) & = 71\end{matrix}

1:

$3+2\times(36-4)=67$

2:

$3\times2+36\times4=150$

3: (added for completeness - thanks MCN)

$(3+2)\times36-4=176$

4:

$3+(2\times36)-4=71$
