One can obtain a total of $16$ using each of the numbers $10, 12, 14$, and $17$ exactly once, combining them using any of the four common operations $+$, $-$, $*$, and $/$ along with parentheses, by writing $10/(17-12)+14$. Demonstrate how to obtain $2$.
I know how to do this, but is there any way to do it without bashing?
These type of questions do not have any particular method to solve them. You have to derive answers from options if options are given. And in case no options use brute force to solve them like in this case.
