Everyone , pay attention . In this question , the BODMAS rule ( Bracket , Off , Division , Multiplication , Addition , Subtraction ) is used . Let me explain it . First transform all the signs . The ans . comes 36 - 12 -:- 4 6 -:- 2 x 3 . First we have to do division , then multiplication , then addition and then subtraction . Therefore :-36 - 12 -:- 4 6 -:- 2 x 3 \l/36 - 3 3 x 3 \l/ 36 - 3 9 \l/ 36 - 12 \l/ 24
