# Discrete Mathematics

Welcome to this course!

A course of Discrete Mathematics has more than one objective. To deal with a problem, students need to study a congregation of all mathematics information and how to process them by reasoning or inductive reasoning in order to give out the results handling the problems. More importantly, with this course, students need to know how to think logically and mathematically. To achieve these goals, there are a lot of mathematical skills to be gained. Five significant skills are nested in learning Maths: mathematical reasoning, combination analysis, discrete structure, algorithmic thinking, application, and modeling. A successful discrete math course should carefully mix and balance all these five topics.

1 - Mathematical Reasoning: Students must understand mathematical reasoning in order to read, understand, and construct mathematical reasoning. This course begins with mathematical logic problems and it is the basis for the next knowledge, for problems to be proved later. Mathematical induction is emphasized through many different types and it shows that it is a valid proof.

2 - Combination Analysis: An important problem-solving skill is the ability to enumerate objects. This course gives an introduction to the basic technique of counting applied in the complexity analysis techniques of the later algorithm for students studying computer science.

3 - Discrete Structure: A course in Discrete Mathematics. Thus, students will know how to work with discrete structures, which are the abstract mathematical structures used to represent discrete objects and relationships among objects. Discrete structures include sets, permutations, relations, graphs, trees, and finite elements.

4 - Algorithmic Thinking: After an algorithm has been described, a computer program can be constructed to execute it. The mathematical part of this operation, which includes algorithm specifications and the verification that it works properly, and the analysis of computer memory and the necessary time to execute it, all are identified in this course.

5 - Application and Modeling: Discrete Mathematics has applications for almost every imaginable area and has been studied. There are many computer science applications in this course, as well as applications for different areas such as chemistry, botany, zoology, linguistics, geography, business, and Internet.

Once again, welcome you and wish you much knowledge and many skills from this course!
