The cardinality of the empty set is 0. A one-to-one correspondence between sets A and B can be explained as each object in A is paired with one and only one object in B ...that there should be a larger set of numbers, say R such that there is a correspondence between R and the points of this straight line. Indeed, one can construct such a set of numbers from the rational number system Q, called set of real numbers, which contains the set of rationals and also numbers such as p 2; p 3; p 5 and more. Moreover, on ...Sets - An Introduction. A set is a collection of objects. The objects in a set are called its elements or members. The elements in a set can be any types of objects, including sets! The members of a set do not even have to be of the same type. For example, although it may not have any meaningful application, a set can consist of numbers and names.To perform arithmetic operations, these numbers are required. Imaginary and unreal numbers are a part of complex numbers. In this chapter, students will learn all the important definitions, understand real numbers in depth, properties, such as cumulative, associative, distributive, and identity. Exercise 1.1.
