One of the first great intellectual feats of a young child is learning how to talk, closely followed by learning how to count.
From earliest childhood we are so bound up with our system of numeration that it is a feat of imagination to consider the problems faced by early humans who had not yet developed this facility.
Careful consideration of our system of numeration leads to the conviction that, rather than being a facility that comes naturally to a person, it is one of the great and remarkable achievements of the human race.
It is impossible to learn the sequence of events that led to our developing the concept of number.
Even the earliest of tribes had a system of numeration that, if not advanced, was sufficient for the tasks that they had to perform.
Our ancestors had little use for actual numbers, instead their considerations would have been more of the kind is this enough?
Rather than How many?
When they were engaged in food gathering, for example.
However, when early humans first began to reflect on the nature of things around them, they discovered that they needed an idea of number simply to keep their thoughts in order.
As they began to settle, grow plants and herd animals, the need for a sophisticated number system become paramount.
It will never be known how and when this numeration ability developed, but it is certain that numeration was well developed by the time humans had formed even semi-permanent settlements.
Evidence of early stages of arithmetic and numeration can be readily found.
The indigenous people of Tasmania were only able to count one, two, many, those of South Africa counted one, two, two and one, two twos, two twos and one, and so on.
But in real situations the number and words are often accompanied by gestures to help resolve any confusion.
For example, when using the one, two many type of system, the word many would mean, look at my hands and see how many finger I am showing you.
This basic approach is limited in the range of numbers that it can express, but this range will generally suffice when dealing with the simpler aspects of human existence.
The lack of ability of some cultures to deal with large numbers is not really surprising.
European languages, when traced back to their earlier version, are very poor in number word and expressions.
The ancient Gothic word for ten, tachund, is used to express the number 100 as tachund tachund.
By the seventh century, the word teon had become interchangeable with the tachund or hund of the Anglo-Saxon language, and so 100 was denoted as hund teontig, or ten times ten.
The average person in the seventh century in Europe law a man had to be able to count to nine!
