Multiplication of Signed Numbers as Volume, by Verne Peterson, Chicago, 2011

‘There is something especially gratifying in a geometric representation or proof of an abstract concept. If that concept can be recreated and shown to be consistent in our familiar physical environment, a more profound understanding may be reached. I find that many people, myself included, are left unsatisfied by algebraic explanations of why the product of two negative numbers is a positive number. If only it could be demonstrated with something tangible like blocks?’
