![]() ![]() It was not until the 15 th century that the symbols that we are familiar with today first took form in Europe. The development of these ten symbols and their use in a positional system comes to us primarily from India. We’ll explore base systems more thoroughly later. For example, the position of the symbol 3 in the number 435,681 gives it a value much greater than the value of the symbol 8 in that same number. Furthermore, this system is positional, which means that the position of a symbol has bearing on the value of that symbol within the number. This is a base-ten (decimal) system since place values increase by powers of ten. Thus, eleven comes from Old English endleofan, literally meaning “ one left ,” and twelve from twelf, meaning “two left” the endings -teen and -ty both refer to ten, and hundred comes originally from a pre-Greek term meaning “ten times. The special position occupied by 10 stems from the number of human fingers, of course, and it is still evident in modern usage not only in the logical structure of the decimal number system but in the English names for the numbers. Some ancient symbols for 1 and 10 are given in the figure. These symbols appeared in Egypt as early as 3400 bce and in Mesopotamia as early as 3000 bce, long preceding the first known inscriptions containing numerals in China ( c. In fact, the earliest numerals of which there is a definite record were simple straight marks for the small numbers with some special form for 10. ![]() When it became necessary to count frequently to numbers larger than 10 or so, the numeration had to be systematized and simplified this was commonly done through use of a group unit or base, just as might be done today counting 43 eggs as three dozen and seven. The abstract notion of two, signified orally by a sound independent of any particular objects, probably appeared very late. Vocal sounds were probably used to designate the number of objects in a small group long before there were separate symbols for the small numbers, and it seems likely that the sounds differed according to the kind of object being counted. Having no fixed units of measure, no coins, no commerce beyond the rudest barter, no system of taxation, and no needs beyond those to sustain life, people had no necessity for written numerals until the beginning of what are called historical times. Judging by the habits of indigenous peoples today as well as by the oldest remaining traces of written or sculptured records, the earliest numerals were simple notches in a stick, scratches on a stone, marks on a piece of pottery, and the like. Probably the earliest way of keeping record of a count was by some tally system involving physical objects such as pebbles or sticks. Just as the first attempts at writing came long after the development of speech, so the first efforts at the graphical representation of numbers came long after people had learned how to count. Numerals and numeral systems, symbols and collections of symbols used to represent small numbers, together with systems of rules for representing larger numbers.
