  Mathematics is the logical study of the numerical and particular relationship among different objects. Mathematics can be broadly grouped into the following branches: Arithmetic : It is the oldest and the most elementary among other branches of mathematics. It deals with numbers and the basic operations like addition, subtraction, multiplication, and division, between them. Algebra : It is a kind of arithmetic where we use unknown quantities along with numbers. These unknown quantities are represented by 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 and also helps you find the unknown missing values in the algebraic expressions and equations. 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. Trigonometry : Derived from two Greek terms, i.e., t...
