Document Summary

Numbers, measures, words: numbers, families of numbers, counting vs. measuring, numbers vs. numerals, measures, contrast, indicator, score, scoring method, range of convenience, issues of representativeness, words, structure of a word, phonemic ambiguity, lexical ambiguity, garden path effect. Is obviously something used to count (cid:862)(cid:272)ou(cid:374)ta(cid:271)le(cid:863) thi(cid:374)gs: there are families of numbers, natural number (cid:1005), (cid:1006), (cid:1007) i. e. counting numbers, whole number (cid:1004), (cid:1005), (cid:1006), (cid:1007) (has 0 + natural numbers) Integers - -3, -2, -(cid:1005), (cid:1004), (cid:1005), (cid:1006) (consists of 0, natural numbers, negative counterparts: a number is a point on a linear continuum, the continuum is made up of the real numbers. Irrational number: does not end or repeat a sequence (e. g. pi=3. 1415926 (cid:895) Real numbers are used to measure, and all other numbers are used to count. But so(cid:373)eti(cid:373)es (cid:374)u(cid:373)erals do not represent numbers at all. Every measurement instrument has a range of convenience that results from its design to serve a particular purpose.
