Real Numbers Rational Numbers Irrational Numbers Integers Whole Numbers Counting Numbers .Operations on the set of Real Numbers . In algebra. now performed with positive and negative of arithmetic are extended to negative . computations are numbers. In this chapter, we review some properties of the real numbers R and its subsets. We dont give proofs for most of the results stated here. 1.1. Completeness of R. Intuitively, unlike the rational numbers Q, the real numbers R form a continuum with no gaps. All Real Numbers that are NOT Rational Numbers cannot be expressed as fractions, only non-repeating, non-terminating decimals 2 , 35 , 21, 381, 101 , , , . Even roots (such as square roots) that dont simplify to whole numbers are irrational. In my post about the countability of the rational numbers, I said that Id come back to the topic and prove that the real numbers are uncountable. Thats the plan for today. If youre not familiar with the definition of countability, please read that post first: this really is part two of that post. But we sometimes use another system for writing numbers - "Roman numerals". The Romans used letters of the alphabet to represent numbers, and you will occasionally see this system used for page numbers, clock faces, dates of movies etc.xxi.

Numbers, Real A real number line is a familiar way to picture various sets of numbers.

For example, the divisions marked on a number line show the integers, which are the counting numbers 1, 2, 3,x 2. Nested Intervals and Completeness 5. Axiomatic Definition of Real Numbers 1. The Natural Numbers, the Integers, and the Rational Numbers in the Real Number Field. These axioms imply all the properties of the real numbers and, in a sense, any set satisfying them is uniquely determined to be the real numbers. The axioms are presented here as rules without very much justication. Other approaches can be used. If x is a real number, then we define for the positive numbers sqrt(x)"sup"yinRR:y2
