When starting on number work, most of us start by counting on our fingers. This must have been true throughout history, as we have ten fingers, and base ten is so common in early number systems. In fact, a single symbol within a number is called a digit, and this word comes from the Latin for finger, digitus. So fingers are the oldest calculating machines.

The Babylonians had a way of counting up to 60 on their fingers - see Babylonian Numbers.
