Real Number System

The Set of Numbers Natural Numbers Whole Numbers Integers The set of natural numbers contains {1, 2, 3,…} Whole Numbers The set of whole numbers contains {0, 1, 2, …} Integers The set of integers contains {…, -3, -2, -1, 0, 1, 2, 3, …}

Set of Real Numbers, cont’d Rational Numbers –the set of all numbers that can be expressed as a quotient of integers Irrational Numbers – the set of all numbers that correspond to points on the number line but that are not rational numbers. That is, an irrational number is a number that cannot be expressed as a quotient of integers. Real Numbers – is the set of all numbers each of which correspond to a point on the number line.
