# Is Discrete Math the Same as Calculus?

When it comes to mathematics, many people tend to think of it as one giant subject without separating it into different areas. However, math is a complex field that can be broken down into several sub-fields such as calculus, geometry, algebra, statistics, and discrete mathematics. In this article, we will focus on two of the most popular areas in math – Discrete Mathematics and Calculus.

## What is Discrete Mathematics?

Discrete Mathematics is the study of mathematical structures that are discrete rather than continuous. It deals with structures of distinct objects and the relationships among them. These structures could be anything – graphs, sets, sequences, functions, or even computer algorithms.

Combinatorics, set theory, and graph theory are usually core elements in a discrete math course. It is a crucial aspect of computer science and has several applications in real-life, such as cryptography, computer networking, and database management.

## What is Calculus?

Calculus is a branch of mathematics that deals with continuous change and motion. It is concerned with the study of functions, limits, derivatives, integrals, and infinite series. Calculus is used to describe and analyze natural phenomena such as motion, growth, and decay.

Calculus is inherent in every other subject, even discrete structures. Discrete Mathematics comes in mind. But calculus is already inherent in discrete mathematics.

## Is Discrete Mathematics the Same as Calculus?

No, Discrete Mathematics is not the same as Calculus. Discrete Mathematics is a branch of mathematics that deals with structures of distinct objects, while Calculus is concerned with continuous change and motion. In other words, Discrete Mathematics deals with objects that can be counted while Calculus deals with objects that are continuous.

Despite their differences, Calculus is already inherent in Discrete Mathematics. This is because many of the concepts of Calculus, such as limits, derivatives, and integrals, are used in discrete structures. For example, the rate of change of a function is the derivative of the function, and in discrete structures where the function is represented by a sequence, the derivative can be expressed as the difference quotient of the sequence.
