The meaning of 1+1 is a transition between two states. The machine is in state A before the expression is processed and is in state B after the processing ends (usually, A and B are different states, albeit in some cases A is the same as B). A and B are stored in cells of memory (usually: A and B are distributed over many binary cells). The binary cells can in some cases influence the emission of photons (such as: bits of GPU's frame-buffer; the placement of particles of black powder on a white paper coming from a printing machine). -atom [We seem to be pretty deep in this tarpit now. -John]
