is not so much an adding machine, calculator, or computer as it is a mere visual record of the computations going on in the mind of the person using it.

Ever seen an abacus? You know, those centipedelike things with wooden beads in rows. They’re sold mostly in knickknack import shops, for wall decoration. But, in fact, an abacus is an adding machine, calculator, and computer. On second thought, that’s not quite true. The abacus is just a visual record of the computations going on in the mind of the person using it.
