 May 14, 2013 Comparing Numbers by: Staff AnswerThe real number system we use has two separate properties which are worth mentioning:CardinalityOrdinalityCardinality is the total number of possible numbers (elements) in the set of all Real Numbers (which of course is infinite).Cardinality does not take the order of the numbers into account. There are just an infinite number of Real Numbers available, all jumbled together.As an example, set A = {1, 2, 3, 4, 5} is the same as A = {4, 5, 3, 1, 2}. In this example, the cardinality of set A is 5 because there are five elements in the set. The cardinality of a set is always a zero or a positive integer.Ordinality is the relative position of a number with respect to other numbers.This is the question you are asking: What are the relative positions of -1 and -3.5 in the sequence of all real numbers? The easiest way to answer this question is to plot both numbers on a number line.The number to the right is the largest number. The number to the left is the smallest number.
