9(n+3) + 4(n+8) multiply out the brackets and simplify

$${\mathtt{9}}{\mathtt{\,\times\,}}\left({\mathtt{n}}{\mathtt{\,\small\textbf+\,}}{\mathtt{3}}\right){\mathtt{\,\small\textbf+\,}}{\mathtt{4}}{\mathtt{\,\times\,}}\left({\mathtt{n}}{\mathtt{\,\small\textbf+\,}}{\mathtt{8}}\right) = \left({\mathtt{9}}{n}{\mathtt{\,\small\textbf+\,}}{\mathtt{27}}\right){\mathtt{\,\small\textbf+\,}}\left({\mathtt{4}}{n}{\mathtt{\,\small\textbf+\,}}{\mathtt{32}}\right) = {\mathtt{9}}{n}{\mathtt{\,\small\textbf+\,}}{\mathtt{27}}{\mathtt{\,\small\textbf+\,}}{\mathtt{4}}{n}{\mathtt{\,\small\textbf+\,}}{\mathtt{32}} = {\mathtt{13}}{n}{\mathtt{\,\small\textbf+\,}}{\mathtt{59}}$$
