The cardinality of a set is nothing but the number of elements in it. For example, the set A = {2, 4, 6, 8} has 4 elements and its cardinality is 4. Thus, the cardinality of a finite set is a natural number always. The cardinality of a set A is denoted by |A|, n (A), card (A), (or) #A. But the most common representations are |A| and n (A).Any rational number can be represented as either: a terminating decimal: 15 8 = 1.875, or. a repeating decimal: 4 11 = 0.36363636⋯ = 0. ¯ 36. We use a line drawn over the repeating block of numbers instead of writing the group multiple times. Example 1.2.1: Writing Integers as Rational Numbers.Math inside RMarkdown. In side a text chunk, you can use mathematical notation if you surround it by dollar signs $ for “inline mathematics” and $$ for “displayed equations”.
