48/2(9+3), some say its 288 and some say its 2. I think it is 288.

48/2 * (9+3) = 24 * 12 = 288        I think this is right !

$${\frac{{\mathtt{48}}}{{\mathtt{2}}}}{\mathtt{\,\times\,}}\left({\mathtt{9}}{\mathtt{\,\small\textbf+\,}}{\mathtt{3}}\right) = {\mathtt{288}}$$

48 : (2*(9+3)) = 48 : (2*12) = 48 : 24 = 2

$${\frac{{\mathtt{48}}}{\left({\mathtt{2}}{\mathtt{\,\times\,}}\left({\mathtt{9}}{\mathtt{\,\small\textbf+\,}}{\mathtt{3}}\right)\right)}} = {\mathtt{2}}$$
