### Chapter 1 : Real Numbers

Real Numbers? So you must be wondering, aren't all numbers real? Are there unreal numbers? Well, let us solve your confusion right here. The easiest way to remember is that if the number can be put on a number line, it is a real number. Let's find out some more interesting concepts about real numbers:

### Chapter 2 : Polynomials

Polynomials are mathematical expressions with any number of variables and coefficients. Polynomials find applications in various fields of Maths and Science. Polynomials have their own set of laws and rules for arithmetics. In this chapter, we will learn everything about polynomial and its applications.

### Chapter 3 : Pair of Linear Equations in Two Variables

Linear equations are frequently applied in our daily lives. You must have come across the famous mangoes and oranges problems. And do you know how to solve them? Well, in this section we will learn about what are and how to solve a pair of linear equations in two variables, as well as the consistency of equations.

### Chapter 4 : Quadratic Equations

In the Arithmetic Aptitude test, the questions are based on the concepts of Quadratic Equations, Approximations and Simplifications, Data Sufficiency, and HCF and LCM. The following set of topics will not only help you solve any question from this section but solve it within one minute, with proper practice.

### Chapter 7 : Coordinate Geometry

Vidoe games are fun to play, especially because of depth, and movement in them. But how is this created? Well, the simple answer to this is 'geometry'. Geometry allows us in determining how the shapes and figures fit together to maximize efficiency. So, let us get acquainted with geometry basics ideas!

### Chapter 9 : Some Applications of Trigonometry

Trigonometry is the branch of mathematics that deals with the understanding of the relationship between various properties of a triangle. Trigonometry has found its application in the field ranging Engineering to Art and Architecture to Astronomy. In this chapter, we will learn about some applications of Trigonometry.

### Chapter 11 : Constructions

Geometry is the study of shapes and sizes and relative positions and proportions of objects. Constructions of shapes is a tricky but very important part of Geometry. It is difficult to understand because construction is done step by step. If you miss or do any of the steps wrong, you end up with something vague.

### Chapter 12 : Areas Related to Circles

Finding areas and perimeters of squares, rectangles, triangles etc a piece of pie right? But what about finding the area of a piece of pie? Well, it isn't that difficult. Let us learn how to calculate the area of a circle and some concepts of areas related to circles.

### Chapter 13 : Surface Areas and Volumes

We live in a three-dimensional world. The room you are sitting in can be described by these dimensions. A football would eventually burst if you forcefully try to pump in more air than required. The dimensions and capacities of these objects can be measured by studying its Surface Area and Volume.

### Chapter 14 : Statistics

Statistics is all around you. Did you know there are so many daily things in your life that are made easy and exciting by statistics? Without statistics, you wouldn't have all the stats on your favourite football payer, or track your progress in your exams, or have weather forecasts etc.
