A set is a collection of mathematical objects. Mathematical objects can range from points in space to shapes, numbers, symbols, variables, other sets, and more. Each object in a set is referred to as an element. Below are a few examples of different types of sets.Some sets are commonly used. N : the set of all natural numbers. Z : the set of all integers. Q : the set of all rational numbers. R : the set of real numbers. Z+ : the set of positive integers. Q+ : the set of positive rational numbers. R+ : the set of positive 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).Since 1 is an element of set B, we write 1∈B and read it as '1 is an element of set B' or '1 is a member of set B'. Since 6 is not an element of set B, we write 6∉B and read it as '6 is not an element of set B' or '6 is not a member of set B'.. 3. Specifying Members of a Set. In the previous article on describing sets, we applied set notation in describing sets.For Example, a set of all the prime numbers less than or equal to 10 is given as P = {p : p is a prime number ≤ 10}. In another example, the set of Natural Numbers in set builder form is given as N = {n : n is a natural number}. Read More on Representation of Sets. Types of Sets.

There are several special sets of numbers: natural, integers, real, rational, irrational, and ordinal numbers.These sets are named with standard symbols that are used in maths and other maths-based subjects. For example, mathematicians would recognise Z to define the set of all integers. Here is a list of commonly used mathematical symbols with names and meanings. Also, an example is provided to understand the usage of mathematical symbols. x ≤ y, means, y = x or y > x, but not vice-versa. a ≥ b, means, a = b or a > b, but vice-versa does not hold true. .Later in this course we will introduce numbers beyond the real numbers. Figure \(\PageIndex{3}\) illustrates how the number sets we’ve used so far fit together. Figure \(\PageIndex{3}\). This chart shows the number sets that make up the set of real numbers. There is no restriction on the number of different sets a given element can belong to, except for the rule that a set cannot be an element of itself. The number of elements in a set may be infinite. E.g., \(\mathbb{Z}, \mathbb{R},\) and \(\mathbb{C}\), denote the sets of all integer, real, and complex numbers, respectively.A natural number can be used to express the size of a finite set; more precisely, a cardinal number is a measure for the size of a set, which is even suitable for infinite sets. This concept of "size" relies on maps between sets, such that two sets have the same size, exactly if there exists a bijection between them.Tutorial 2: Symbols and Sets of Numbers.
