Vector coordinates help

Hello all. My mortise and tenon script is still a WIP and I have ran into yet another problem. I am using the corner of a rectangle as the reference point for an skRectangle() function. Suppose the coordinates of the corner are (-50, 50)*mm in the x-z plane, and I want to put a point that is 10mm across and 5mm down, I have a problem. This is because if I just say (-50,50) + (10,-5) using this corner, the point ends up here:

However, if I use the other corner with coordinates (50,50)*mm, I can't just do (50,50) + (10,-5) because the point ends up here:

How could I set this up such that it doesn't matter which corner is selected without using lots of if statements?
Thanks
