Question

16 x 18, I double and halve

Answer 1

16*18 is 288 

what do u mean by "I double and halve"

Answer 2

I'm not exactly sure what you mean but here is what I got from that:

                    16x18=288

                 288x2=576

                    576/2=288

I'm not exactly sure if this is what you wanted as I am not fully able to comprehend the question.
