$$\left(-{\mathtt{2}}\right){\mathtt{\,\times\,}}\left(-{\mathtt{2}}\right){\mathtt{\,\times\,}}\left(-{\mathtt{3}}\right){\mathtt{\,\small\textbf+\,}}{\mathtt{5}}{\mathtt{\,\small\textbf+\,}}\left({\mathtt{4}}\right){\mathtt{\,-\,}}\left({\mathtt{3}}\right) = -{\mathtt{6}}$$
$$\left({\mathtt{24}}\right){\mathtt{\,-\,}}\left({\mathtt{18}}\right) = {\mathtt{6}}$$
Danke radix
