Should you be interested in majoring mathematics, you might find mathematics unique and beautiful, or, perhaps, you simply love dealing with numbers. However, what is mathematics? Math is the study of numbers, shapes, and space using reason and usually a special system of symbols and rules for organizing them. Before getting to know branches of mathematics, you should know what pure mathematics, applied mathematics, and general mathematics are.

There are many branches and sub-branches in mathematics. Most of them connect to one another in many ways, so there's no definite answer to that question. Here are some branches of mathematics

- **Analysis:** It is the branch that deals with the study of the rate of change of different quantities, which also includes the study of functions, calculus, differential equations, etc. To get in detail, it focuses on measure theory, complex analysis, geometric analysis, harmonic analysis, stochastic analysis, calculus of variation, functional analysis, and multivariate & vector analysis. It is perhaps the branch of mathematics that has the most obvious and direct applications to other sciences. In the analysis, you study the ways in which a certain quantity behaves when it depends on one or several parameters, like the position of a ball thrown by a football player depending on time and on how he launched it. I'd say it takes its origins in Descartes' work and was developed a lot by Newton and Leibniz, and those who came after them.

- **Algebra:** It is a kind of arithmetic where we use unknown quantities along with numbers. These unknown quantities are represented with letters of the English alphabet such as X, Y, A, B, etc. or symbols. The use of letters helps us to generalize the formulas and rules that you write and also helps you to find the unknown missing values in the algebraic expressions and equations. It includes linear algebra, abstract algebra, and number theory.

- **Geometry:** It is the most practical branch of mathematics that deals with shapes and sizes of figures and their properties. The basic elements of geometry are points, lines, angles, surfaces, and solids. It focuses on topology, discrete geometry (or combinatorial geometry), manifold, differential geometry, convex geometry and etc.

- **Combinatorics: **the branch of mathematics dealing with combinations of objects belonging to a finite set in accordance with certain constraints, such as those of graph theory. It includes graph theory, external combinatorics, and enumerative combinatorics.

Usually, people often think majoring in mathematics means being a math teacher. It is not true. Mathematics is versatile since every field needs math. For example, math graduates can calculate the probability for business companies such as insurance companies to maximize the profits, or they simply work in the engineering field, or even working with information technology. So, the job includes actuarial analyst, chartered certified accountant, data analyst, investment analyst, statistician, systems developer, insurance underwriter, software tester, financial manager, operational researcher, or even financial trader.

Should you be interested in majoring in mathematics, the Royal University of Phnom Penh (RUPP) is the best choice for you.
