I need help with set up. So on the left side box n positive side I have 3 rectangular boxes colored in (3x) and 3 small boxes one colored two are not (1)(-2). Then on the negative side only one colored box -(1). So would this be 3x+1+(-2)-(1) ?

On the right side box on positive side has 1rectagular box (1x) then 4 small boxes 1 colored 3 not (1)+(-3).on the negative side 6 small boxes colored -(6). So would that be x+1+(-3)-6?

We cannot see the boxes, and your explanation is not clear enough to give a response.
