The real number (ℝ) symbol is a versatile symbol in mathematical expressions and scientific fields used to represent the set of all real numbers. 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). Mathematicians also play with some special numbers that aren't Rea Thus, real numbers broadly include all rational and irrational numbers. They are represented by the symbol R and ...It cannot be both. The sets of rational and irrational numbers together make up the set of real numbers.
