I've had a reality in which 0 (zero) things makes two things ... [particle-antiparticle pairs appearing in quantum fluctuations in vacuo in case that's too terse].

Similarly thousands of things can make up a single thing. [Like bosons in a Bose-Einstein Condensate].

Or in the case in point where you just stick various particles in a pot and pull out some other particles with corresponding energy. For example in beta decay a neutron changes to a proton emitting a W- particle which itself decays to an electron and electron-anti-neutrino (http://en.wikipedia.org/wiki/File:Beta_Negative_Decay.svg).

Ultimately maths is axiomatic, so not universal, and Godel shows that it's not absolute.
