Quantities can be used as being infinitesimal, arguments of a function, variables in an expression (independent or dependent), or probabilistic as in random and stochastic quantities. In mathematics, magnitudes and multitudes are also not only two distinct kinds of quantity but furthermore relatable to each other.
The English language has a number of words that denote specific or approximate quantities that are themselves not numbers. [1] Along with numerals, and special-purpose words like some, any, much, more, every, and all, they are quantifiers. Quantifiers are a kind of determiner and occur in many constructions with other determiners, like articles ...
Some words that have a precise numerical definition can be used indefinitely. For example: couple (2), [21] dozen (12), score (20); myriad (10,000). When a quantity word is prefixed with an indefinite article then it is sometimes intended or interpreted to be indefinite. For example, "one million" is clearly definite, but "a million" could be ...
Quantities set via definition (as opposed to measured quantities) should be given first in the units used in the definition, even if this makes the structure of presentation inconsistent: During metrication, the speed limit was changed from 30 mph (48 km/h) to 50 km/h (31 mph).
Some theories of grammar use the word "numeral" to refer to cardinal numbers that act as a determiner that specify the quantity of a noun, for example the "two" in "two hats". Some theories of grammar do not include determiners as a part of speech and consider "two" in this example to be an adjective .
Oxford English Dictionary, 1933. The study of the measurement, properties, and relationships of quantities and sets, using numbers and symbols. [17] American Heritage Dictionary, 2000. The science of structure, order, and relation that has evolved from elemental practices of counting, measuring, and describing the shapes of objects. [18]
A systems of quantities relates physical quantities, and due to this dependence, a limited number of quantities can serve as a basis in terms of which the dimensions of all the remaining quantities of the system can be defined. A set of mutually independent quantities may be chosen by convention to act as such a set, and are called base quantities.
In modern notation it says that given quantities p, q, r and s, p:q>r:s if there are positive integers m and n so that np>mq and nr≤ms. As with definition 3, definition 8 is regarded by some as being a later insertion by Euclid's editors. It defines three terms p, q and r to be in proportion when p:q∷q:r.
