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).
