CHAPTER XVI

DENOMINATE NUMBERS

186. Uses of Measurement. — Practically everything we buy and sell is measured. We buy meat by the pound, cloth by the yard, land by the acre, and milk by the quart. We describe our houses, our machinery, and even our horses by giving their dimensions.

Buildings and machinery are designed and the dimensions of the various parts are specified. These parts are "made to measure," often in distant places, but when brought together and assembled they fit properly into their places because the measurements were correctly made and faithfully followed out.

One of the most important differences between uncivilized and civilized peoples is that the latter make extensive use of measuring, while the former have no definite means of finding the exact magnitude of a quantity. The Indian would say much," or "heap much," and that is about as near as he could come to a definite expression of a magnitude. Civilized peoples designate quantities definitely as so many times certain units.

187. Definition of Measurement.

Measurement is the process of finding the magnitude of a quantity by comparing it with a certain magnitude of the same kind, called a unit of measure.

188. Denominate Numbers. - Denominate numbers are expressed in terms of units of measurement, which have been established by law or by custom.

Thus, 8 feet, 6 quarts, 18 pounds, 4 hours, are denominate numbers.

189. Simple Denominate Numbers. A simple denominate number is expressed in terms of one unit only.

Thus, 5 yards, 15 acres, 18 cubic feet are simple denominate numbers.

190. Compound Denominate Numbers. A compound denominate number is expressed in terms of two or more units.

Thus, 5 yards 2 feet, 2 pounds 3 ounces, are compound denominate numbers.
