Why Do We Need to Learn Set Theory?


Sets are a facet of maths that seem to just be there, yet they help with many things. We generally define the domain and range of functions in the form of sets. Also, functions are, in particular, simply unique mappings between sets. We have many applications of sets in mathematics and our daily existence. Beginning from sets, we can practise probability and then lead toward statistics. Similar to numbers, we can perform different operations on sets too. Algebra in sets helps students to solve many mathematical problems in all its other branches. Let’s understand the importance of learning set theory here.

We know that some mathematical concepts such as Fourier analysis have practical applications, whereas the purpose of set theory is not practical application. For most mathematicians, the benefit of a set theory is not in any particular theory, it is simply in the language it provides us. However, in recent days, set theory has been used in many areas; for example, computer scientists express their fundamental concept called Turing machines using the language of set theory. Thus, sets in maths are used in many areas to ease the simplifications. Without specific definitions, it is challenging to solve any complex mathematical problem.

Studying set theory, even naively, is the professional point of how to manipulate infinite sets. Modern mathematics is involved with several infinite sets, including smaller and larger sets, and it is good to learn about infinite sets if one wants to understand mathematical objects thoroughly. Also, they can study many set theory related topics under the guidance of a tutor who can deliver the Axiomatic set theory using real-life examples. Furthermore, this kind of learning must involve discussions about the choice hypothesis regarding ordinals and cardinals. In maths, ordinals and cardinals are two ways of counting, which extend beyond our intuitive recognition that natural numbers do counting and allow us to count infinite objects.

We know that students can learn basic set theory concepts in Class 11. Also, NCERT solutions class 11 maths helps practise where and how to apply set theory operations effectively. On the other hand, Axiomatic set theory is a mathematical discipline like any other, and it has a distinct type of typical problem. Set theorists work under their standard or atypical ways to solve them or understand them better. Thus, set theory has many advantages in mathematics. Besides, we have many applications of set theory in the real world.

The study of set theory is essentia, mainly because it serves as a basis for the rest of the concepts in mathematics, and it provides the axioms on which the rest of mathematics is built. Thus, we can say that set theory is commonly employed as a foundational system for the whole of mathematics. Besides its foundational role, the set theory also contributes to developing a mathematical theory of infinity. Also, it has many applications in computer science, philosophy, formal semantics, etc. So, considering the applications of set theory in multiple areas, one should understand the importance of learning it from basics to advanced properties.
