Each integers can be written in the form of p/q.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 rational number is a number that can be expressed as a fraction p/q where p and q are integers and q!=0. A rational number p/q is said to have numerator p and denominator q. Numbers that are not rational are called irrational numbers. The real line consists of the union of the rational and irrational numbers.Symbolism is a device in which an object, person or situation is given another meaning beyond its literal one–usually something more abstract or non-rational than the symbol itself. There are many kinds of symbols.Sets of Numbers: In mathematics, we often classify different types of numbers into sets based on the different criteria they satisfy. Since many of the sets of numbers have an infinite amount of numbers in them, we have various symbols we can use to represent each set since it would be impossible to list all of the elements in the set.Rational number, in arithmetic, a number that can be represented as the quotient p/q of two integers such that q ≠ 0.
