Frequently Asked Questions
Q1: What is discrete mathematics?
A1: Study of countable, otherwise distinct and separable mathematical structures are called as Discrete mathematics. It focuses mainly on finite collection of discrete objects. The field has become more and more in demand since computers like digital devices have grown rapidly in current situation.
Q2: What are Cominatorics?
A2: Combinatorics is the mathematics of arranging and counting. Though a lot of people know how to count, combinatorics uses mathematical operations to count objects/things that are far away from human count in a conventional way. The field also concerned with the way things are arranged which includes rule of sum and rule of product. Permutation and combination come under this topic.
Q3: What are permutations and combinations?
A3: Permutation is an arrangements of things with regards to order where as combination is an arrangement of things without regard to order.
Q4: What is a set theory?
A4: A branch of mathematics concerned with collections of object is called Set theory. The sets could be discrete or continuous which is concerned with the way sets are arranged, counted or combined. A complements of a set A is the set of elements/things/objects which are not in set A. The cardinality of a finite set is the number of elements/things/objects in that set. The way sets can be combined are described by Intersection and Union. Identities for the complements of intersection and union are given by De Morgan's laws.
Q5: What is the difference between discrete and continuous mathematics?
A5: The difference between discrete and continuous mathematics is,
| Discrete mathematics | Continuous mathematics |
| Mathematics focusing on discrete numbers or objects | Mathematics focusing on continuous numbers or the real numbers |
| Discrete mathematics is finite numbers that are not an infinite number of points between the number. | Continuous mathematics focuses on the numbers between any number that is one can always find infinite set of numbers between two numbers. |
| Fundamental set of numbers is the natural numbers. | Fundamental set of numbers that are used for proofs in the interval |
| Graphs is used while studying | Study of topology is applied. |
