Mathematics

A number system is represented by using digits or other symbols in a consistent manner. In this chapter, we will learn the concepts of mathematical operation in several ways such as division formula, divisibility test, unit’s digit, etc.

In this chapter, we will learn in detail the units for counting things and measurements of length, time and weights. This chapter also contains multiple-choice questions to understand the concepts better.

This chapter describes the concept of fractions such as types of fraction, decimal fraction, etc. A fraction tells us how many parts of the whole have been taken. In a fraction, the top number is the numerator and the bottom is the denominator.

This chapter discusses the laws of indices and surds, division method and how to find square root and cube root of a number. This chapter also contains multiple-choice questions based on these concepts.

This chapter explains the method to calculate the HCF and LCM of fractions, decimals, etc. This chapter also contains practise exercises for the students to understand the concepts better.

This chapter explains in detail the concept of simplifying complicated mathematical expression to a simpler form. We will also learn about VBODMAS’ rule which is used when there is more than one operation in an expression.

This chapter discusses in brief the concept of percentage. In this chapter, we will learn the different applications of percentage through some numerical problems which will help students to understand the concept better.

This chapter discusses in brief the concepts of profit, loss and discount. We will also learn the methods and formulas to calculate profit and loss. Students are introduced to new terms such as cost price, selling price and discounts here.

This chapter describes the concept of average. Average refers to the arithmetic mean and it is a common system to calculate the measure of central tendency. This chapter explains the method to calculate the average of a given data.

In this chapter, we will learn the definitions of ratio, partnership and proportion. This chapter also contains multiple-choice questions to understand the concepts better.

In this chapter, we will discuss the problems based on ages. This is explained in detail with help of an example. This chapter also contains multiple-choice questions to understand the concepts better.

This chapter discusses the concept of alligation which helps students to solve problems on topics like mixtures, profit & loss, simple interest, time and distance, etc. We will also learn in detail the mean price and rule of alligation.

This chapter discusses the method and formula to calculate simple and compound interest of a loan or deposit. This chapter also contains multiple-choice questions to synthesize and master the concept.

In this chapter, we will learn to solve questions based on time and work and this chapter also contains multiple-choice questions to synthesize and master the concept.

In this chapter, we will learn problems on pipes and cisterns which are based on the basic concepts of time and work. This is explained in detail with the help of examples.

In this chapter, we will learn in detail the concepts of time, speed, and distance. This chapter also contains multiple-choice questions to synthesize and master the concept.

This chapter discusses the concepts of size, shape, relative position of figures and their properties. We will also learn the formula to calculate parameters, areas of various shapes, etc.

This chapter discusses the concept of measurement of geometric figures and their parameters. This includes 2D and 3D geometric figures and their measurement. We will also learn the formulas to measure figures.

This chapter discusses the concepts of variables, equations, functions, graphs, and more. This chapter also contains multiple-choice questions to synthesize and master the concept.

This chapter discusses the relationship between side lengths and angles of triangles. It helps us to find angles and distance. It also includes trigonometry functions, their sign, formulas, etc.

This chapter discusses the concept of statistics in detail. Statistics is a branch of mathematics that deals with data. It helps us to collect, analyse, interpret and analyse the data in an easily readable form.

This chapter discusses the process of making sense out of a collection of data that has been processed. This includes bar graphs, line graphs, pie charts, tabular forms to show the collection of data, etc.
