The set of real numbers, which is denoted by R, is the union of the set of rational numbers (Q) and the set of irrational numbers ( ¯¯¯¯Q Q ¯ ). So, we can write the set of real numbers as, R = Q ∪ ¯¯¯¯Q Q ¯. This indicates that real numbers include natural numbers, whole numbers, integers, rational numbers, and irrational numbers.Number set symbols. Each of these number sets is indicated with a symbol. ... Because irrational numbers is all real numbers, except all of the rational numbers (which includes rationals, integers, whole numbers and natural numbers), we usually express irrational numbers as R-Q, or R\Q. R-Q represents the set of irrational …The standard symbol for the set of all complex numbers is C, and we'll also refer to the complex plane as C. We'll try to use x and y for real variables, and z and w for complex variables. For example, the equation z = x + yi is to be understood as saying that the complex number z is the sum of the real number x and the real number y times i.May 25, 2021 · 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.
