Various portable counting devices were invented to keep tallies. Merchants who traded goods needed a way to keep count (inventory) of the goods they bought and sold. Then, as even larger quantities (greater than ten fingers and toes could represent) were counted, various natural items like pebbles, sea shells and twigs were used to help keep count. The earliest counting device was the human hand and its fingers, capable of counting up to 10 things toes were also used to count in tropical cultures. It is difficult to imagine counting without numbers, but there was a time when written numbers did not exist. The abacus is one of many types of counting devices which are used to count large numbers.
