Discrete Mathematics

Understanding what is discrete math is often the best approach for a beginner to learn discrete math concepts. In definition, it is a branch of mathematical structure that focuses on countable or separable structures such as graphs and logical statements. Notably, discrete structures can either be finite or infinite, and the subject is the opposite of continuous math that deals with non-separable structures.

Discrete math includes being countable, placed into sets, put into ratios, and arranged systematically. This math field accompanies various rules across different topics, thus providing a suitable introduction to discrete mathematics beginners. More so, several laws such as De Morgan’s laws apply in this area of study. Therefore, the joy of making discrete math interesting is through learning different problem-solving approaches and applying them strategically.

Grand Challenges, Past, and Present

The first theory of Khan academy discrete math was stated in 1852 but got approved in 1976 by Kenneth Appel and Wolfgang Haken. The second problem emerged in 1900 presented by David Hilbert’s list, which suggested that arithmetic axioms are consistent, and the law was disapproved both in 1931 and 1970. Over the years, several events have motivated the evolution of discrete math. Some of them include advances in cryptography and theoretical computer science, telecommunication, and computational geometry.

Several challenges have impacted discrete math, including the link between the complexity classes P ad NP in theoretical computer science. Still, some fields have remained active in addressing these problems, more so those associated with comprehending the tree of life. This has led to the revolution of discrete mathematical structures in modern learning to help solve various life problems.

Topics in Discrete Mathematics

Like different mathematics fields, discrete math comprises several topics to help students solve different discrete math problems. Some topics may be easy to grasp, while it may seem difficult and impractical. That said, here are discrete math topics to know.

Theoretical Computer Science

This topic focuses on specific areas of discrete mathematics that apply to computing. It relies mostly on graph theory and mathematical logic as it offers a theoretical computer science study of algorithms and data structures. This is essentially discrete mathematics for computer science, providing computability studies of computed principles with close ties with logic.

Informational Theory

Informational theory constitutes quantifying information related to coding theory used in designing reliable data transfer and storage methods. It incorporates other continuous topics, including analog encryption, analog coding, and signals. Information theory is among the topics which make discrete math for dummies interesting.


Typically, logic is the study of genuine reasoning and inference principles, including soundness and consistency. Among discrete math examples within this topic is Peirce’s law (((P  Q)  P)  P), which applies in different systems of logic as a theorem. Classical logic examples can be verified using a truth table to provide mathematical proof regarding logic’s importance. There also exist logical formulas as proof used in discrete structures.

Set Theory

This is a branch of mathematics dealing with the studies of sets, usually a collection of objects or the infinite set of prime numbers. Ordered sets with relations often include applications in various areas. When it comes to learning discrete math, the focus remains on countable sets, in this case, finite sets. The study was introduced by Georg Cantor, who provided a distinction between different infinite sets and motivated by trigonometric series studies.


This topic studies the combination or the arrangement of discrete structures. It involves enumerative combinatorics, which deals with counting the number of specific combinatorial objects. Analytical combinatorics is concerned with enumeration using tools such as complex analysis. Combinatorics also include design theory, which is the study of combinatorial designs. Another concept is partition theory that entails studying different enumeration and asymptotic problems associated with integer partitions.

Graph Theory

Graph theory involves the study of graphs and networks, and it is also a part of combinatorics but with more specialized discrete mathematics problems, making a stand as a subject. Graphs are the prime objects in discrete math and the most ubiquitous models. They can model several relations and process dynamics, including social systems, data organization, and computation flow. Though there are continuous graphs, most part falls under discrete mathematics.


Probability enables discrete structures to deal with countable events that occur in sample spaces. This topic has a number range of between 0 and 1 hence used to approximate events. Probability is also useful to calculate continuous situations in discrete probability using numbers. For more constrained situations such as throwing dice, the probability is referred to as enumerated combinatorics.

Number Theory

This type of discrete math topic centers upon properties of general numbers, more so integers. Its applications are likely in cryptography and cryptanalysis based on Diophantine equations, prime numbers, modular arithmetic, and linear and quadratic congruences. Other aspects of number theory are the geometry of numbers, while analytical number theory also applies to continuous mathematics.

Algebraic Structures

Algebraic structures often occur as either discrete or continuous examples. Discrete algebras include Boolean algebra essential for logic gates and programming, relational algebra used in databases, and discrete and finite versions of groups and rings. Other algebras discrete semigroups and monoids saw in formal languages.

Calculus of Finite Differences, Discrete Calculus or Discrete Analysis

A Sequence, a function interval of an integer, could be finite from a data source or infinite from a discrete dynamic system. These discrete functions could be either be defined with a list or formula or given a recurrence relation or difference equation. Difference equations are often used, for instance, when integral transforms in harmonic analysis when studying continuous functions.


Both discrete and combinatorial geometry is about combinatorial features of discrete collections of geometrical structures. The most popular topic in discrete geometry is tiling of the plane. When it comes to discrete math for computer science, computational geometry uses algorithms to geometrical problems.


Topology is a branch of mathematics that validates and generalizes the innate notion of continuous object deformation but includes various discrete topics. This can be readily recognized on topological invariants that uses discrete values. Some of the topics here are finite topological space, combinatorial topology, and computational topology.

Operations Research

These are discrete math techniques used to solve certain problems in engineering, business, and other fields. Some of these problems are practical such as scheduling projects, and include techniques such as linear programming and areas of optimizations and network theory. Operations research also includes continuous topics such as process optimization and continuous-time martingales.

Game, Decision, Utility, Social and Choice Theory

Decision theory involves identifying values, uncertainties, and other relevant issues within a given decision and rationality. Utility theory deals with measuring the comparative economy satisfaction based on the consumption of different goods and services. Social choice theory is about voting, while game theory focuses on situations where success depends on choice.


This discrete mat topic concerns the procedure of moving continuous models and equations to discrete counterparts. The motive is often to make calculations seamless using approximations. Besides, the use of numerical analysis tends to offer important examples.

Discrete Analogous of Continuous Mathematics

Several math concepts have discrete versions, including discrete calculus, discrete dynamical systems, discrete Morse theory, discrete vector measures, and discrete differential geometry. Applied mathematics consists of discrete analog modeling of its continuous counterpart. In algebraic geometry, the curve offers discrete geometries through spectra of polynomial rings over finite fields.

Hybrid Discrete and Continuous Mathematics

Time scale calculus unifies the theory of difference equations together with differential equations. This gives it the properties of discrete math symbols and continuous data. It can also take the approach of the notion of hybrid dynamical systems to create discrete models.
