A patient can't remember having amnesia.

The Romans had no adding machines. Even the art of writing was known to comparatively few people. So they did their adding and subtracting with the aid of little stones used as counters.

The Latin word for the little rock used in this way was calculus, a diminutive of calx, meaning "limestone".

From calculus, the verb calculare, "to calculate", was formed, and its past participle, calculatus, is the immediate origin of English "calculate".
