I am carrying out an Investigation, which involves finding out the diagonal difference for different sized squares on a variety of different number grids. I have managed to complete the squares but I want to move on to investigating rectangles and I am stuck with the algebra for rectangles. Please can any body help!!!

N N+1 N+2
N+10 N+11 N+12
so (N+10)x(N+2) - Nx(N+12)
= {Nsquared +12N + 20} - {Nsquared +12N}
= Always 20 etc for a 3x2 grid
FINAL
Hint If Grid size is pxq result is always 10x(p-1)x(q-1)

What do you mean by "diagonal difference"?!
I can only imagine you're looking for the length of the line between two opposing corners, which is simply given by a^2 + b^2 = c^2 ("a squared plus b squared equals c squared).
I honestly cannot think what else you mean.
