Number is tho name by which we signify how many objects or things are considered, whether one or more. When, for instance, we speak of one horse, two apples, three yards, or four hours, the number of the things referred to will be one, two, three, or four, according to the case; and so one, two, three, four, and the rest, are called numbers. 3. Numbers are considered either as Abstract or Concrete. Abstract numbers are those which have no reference to any particular kind of unit; thus, five, as an abstract number, signifies five units only, without any regard to particular objects. Concrete numbers are those which have reference to some particular kind of unit; thus, when we speak of five horns, six yards, seven horses, the numbers five, sis, seven, are said to be concrete numbers, having reference to the particular units one hour, one yard, one horse, respectively. 4. Arithmetic is the science of Numbers. 5. All numbers in common Arithmetic are expressed by means of the figure 0, commonly called zero or a cypher, which has no value in itself, and nine significant figures, 1, 2, 3, 4, 5, 6, 7, 8, 9, which denote respectively tho numbers one, two, three, four, five, six, seven, eight, nine. These ten figures are sometimes called Digits. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
