The algebra, even a beginner's algebra, is the greatest tool in developing systemic logical thinking that I know of. If you can't manage this, I would trust you, well, probably, to saw a button to my coat, but nothing that requires any highest degree of brain functioning. 'Cause, really, it doesn't come simplier than that on this level. If even that is beyong your abilities... sorry, hon, you're out of any competition as far as I'm concerned.

(You in this case is a collective. :))
