The sets of rational and irrational numbers together make up the set of real numbers. As we saw with integers, the real numbers can be divided into three subsets: negative real numbers, zero, and positive real numbers. Each subset includes fractions, decimals, and irrational numbers according to their algebraic sign (+ or –).

The notation Z for the set of integers comes from the German word Zahlen, which means “numbers”. Integers strictly larger than zero are positive integers and integers strictly less than zero are negative integers. Why set of irrational number is denoted by Q? The symbol Q′ represents the set of irrational numbers and is read as “Q prime”.Apr 17, 2022 · There is no standard symbol for the set of irrational numbers. Perhaps one reason for this is because of the closure properties of the rational numbers. We introduced closure properties in Section 1.1, and the rational numbers \(\mathbb{Q}\) are closed under addition, subtraction, multiplication, and division by nonzero rational numbers. A symbol for the set of rational numbers. The rational numbers are included in the real numbers , while themselves including the integers , which in turn include the natural numbers . In mathematics, a rational number is a number that can be expressed as the quotient or fraction of two integers, a numerator p and a non-zero denominator q. [1]
