Furthermore, it covers the addition and subtraction of decimals, the multiplication of decimals by 10, 100, 1000, etc., the multiplication of decimals by a whole number, and the multiplication of decimals by a decimal. Finally, the chapter concludes with some explained solutions for a decimal division by a whole number.

 

Chapter 4- Rational Numbers

This chapter discusses positive rational and negative rational numbers. The standard form of rational numbers is the main topic in this chapter. It shows that the rational numbers can be represented in the form p/q where q≠0. Any number which is not rational can be deemed as irrational. The chapter clearly differentiates between the two. Additionally, the chapter discusses how rational numbers are represented on the real line. Finally, a brief mention of the comparison and division of rational numbers concludes this chapter.

Chapter 5- Exponents

In Chapter 5, we examine some of the theories and concepts related to the exponential form of numbers. It is the result of multiplying rational numbers several times. The chapter is based on the powers of numbers and how bigger numbers can be expressed as powers of their smaller factors. In addition, this chapter covers exponent laws, large numbers expressed in standard form, numbers expressed in expanded form, and square root concepts. There are several applications of this chapter in the subject of physics, so it is very valuable.

Chapter 7- Linear equations in one variable deal with equations that have the highest power of unity and the theorems related to them. An equation is a statement of equality, which contains one or more unknown quantities or variables. The other concepts explained in this chapter are transposition and conversion of a word problem into equations.

Chapter 8- Ratio and Proportion

Chapter 8- Ratio and Proportion explain the relationship between two entities having a particular common factor (which in some cases could be 1). This chapter deals with the methods to convert larger numbers to their simplest form. Ratios are depicted using a ':' in between two numbers (for example, 2:3 is a ratio). The chapter concludes with explanations for the various relations between the numbers and how to represent them as a ratio. The chapter also includes the concepts of proportion and helps the students understand and find out which ratios or numbers are proportional to each other.

Chapter 9- Unitary method

Chapter 9- Unitary method deals with finding a quantity in relation to the magnitude of another quantity. The value of the first quantity is first obtained to find the value of any other required quantity that shares a specific relation with the first quantity. For example, if 1 bag of apples costs 10 rupees, then 3 bags of apples would cost 3x10=30 rupees. The chapter also covers the topics of direct variation and inverse variation. The concept of the unitary method is also used in the subjects of physics and chemistry, which makes the topic very important to understand and master. It provides an efficient calculation tool that helps to solve various questions in different subjects.

It teaches the students how to represent a percentage in a ratio and convert a given ratio into a percentage. The chapter concludes with the concept of converting a given percentage into its decimal form. The chapter also explains how the method of percentage is efficient in converting information. Finally, there are various practical problems based on the concept of percentage given for practice.

Chapter 11- Profit and Loss

Chapter 11- Profit and Loss deal with the cost price and selling price of the product. It explains the concepts of economy and how the prices of different commodities at which they were bought and sold lead to a profit or a loss. The cost at which a commodity is bought is called its cost price. Similarly, the price at which a commodity is sold is called its selling price. If the cost price is greater than the selling price, then the person involved is said to have suffered a loss. Similarly, if the cost price is less than the selling price, the person involved is said to have gained a profit. The chapter also discusses the concepts of gain percentage and loss percentage.

Chapter 12 - Simple interest

Chapter 12- Simple Interest deals with the system of increment of money based on the rates of interest when some amount of money is deposited, or a loan is taken. For example, if we need to borrow money from a bank or a moneylender for a specified period, we have to pay back the money we borrowed and some additional money for using the lenders' money. The additional money mentioned in this example is calculated by adding the interest at which we borrowed the money. The chapter also explains the use of terms such as principal, interest, amount etc. This chapter is necessary as it is applicable in real-life situations, and knowledge about it would make our lives easier.

Chapter 13- Lines and angles

Chapter 13 deals with vertically opposite angles, supplementary angles, complementary angles, adjacent angles, and linear pair angles. For example, two angles are supplementary if their magnitudes add up to 180 degrees. Similarly, two angles are said to be complementary if their magnitudes sum up to be 90 degrees. Finally, adjacent angles are the angles lying adjacent to a line. These concepts hold many applications in the chapters that follow, and thus, students must understand these concepts thoroughly.

Chapter 14- Properties of Parallel Lines

This chapter deals with the properties of parallel lines. If two lines are parallel, they lie in the same plane, and they do not intersect, but they extend. It is assumed that the parallel lines meet at infinity. The chapter also includes the distance between parallel lines, transversal, angles formed when a transversal cuts two parallel lines. The relationship between these angles formed, the properties of certain angles with respect to each other are also discussed. These relationships and properties provide the aid needed to find the magnitude of these angles.

Chapter 15- Properties of triangles

We explore properties of triangles, such as naming triangles alongside their sides, calculating their angles, calculating their angles sum, calculating exterior and interior opposite angles, calculating the sum of the angles of triangles and applying Pythagoras' theorem in this chapter.

Chapter 16- Congruence

Chapter 16- Congruence deals with the concept of determining if the two given triangles are exactly similar with the same sides and angles or not. It helps determine the congruence of the triangles. Congruence exists when two figures have the same size and shape. In this chapter, the concepts of congruent figures, congruence of triangles, and congruence and area are discussed.

Chapter 17- Constructions

Chapter 17- Constructions deal with the methods, and detailed procedures required to construct different figures based on the type of properties and the requirements asked in the questions. The chapter has more of a hands-on approach, and it involves solving questions to understand each type of construction. It is based on the construction of lines that are inclined to another line at a certain angle or are perpendicular bisectors of another line. The chapter also includes angular bisectors and angular bisectors of angles formed by the sides after constructing a triangle.

Chapter 18- Reflection and Rotational Symmetry

Chapter 18- Reflection and Rotational Symmetry deals with the concepts of reflection and rotational symmetry in which a figure is said to be symmetrical about a line if it is identical on either side of the line of symmetry. A figure is said to have rotational symmetry if the figure remains the same when rotated about a certain point. For example, in the case of 'I', there is a line of symmetry.

Chapter 19 - Three-dimensional shapes

In Chapter 19-Three Dimensional Shapes, solids are discussed, such as cuboids, cubes, cones, cylinders, and spheres. Any figure or any object or any shape with three dimensions such as length, breadth and height is called a three-dimensional shape. The properties of these shapes and the important parameters associated with these solid figures are discussed.

Chapter 20- Mensuration

Chapter 20- Mensuration deals with problems related to the area of a rectangle, a square, parallelograms, triangles and trapezium etc. The chapter explains the formulae required to calculate the volumes and areas of the entities mentioned above in detail.

Chapter 21- Collection and Organization of Data (Mean, Median, and Mode)

Chapter 21- Collection and Organization of Data (Mean, Median, Mode) deals with different grouped or ungrouped data sets. The present-day is information oriented. Therefore, we need information in the form of numerical figures called data. The mean of a given set of data is the average of the magnitudes of the data provided. The mode is the maximum frequency of occurrence of a particular entity in the given set of data. The median is calculated by a few formulae formulated by the great mathematicians in the past, but we shall discuss only 1 method in this chapter. The topics covered in this chapter are ungrouped data, mean of a tabulated data, the median of ungrouped data, the median of discrete series, mode of ungrouped data.

Chapter 22- Bar graphs

Chapter 22- Bar Graphs give a pictorial representation of the numerical data provided in the form of rectangles comprising equal width and varying heights. This chapter deals with depicting a grouped or ungrouped set of data in bar graphs to better represent and understand the data procured. In addition, this chapter teaches us how to draw bar graphs and the different types of graphs prepared with a given set of data.

Chapter 23- Probability

Chapter 23- Probability deals with the concept of chance, which can be explained as the possibility of an event based on the previous occurrences and favourable outcomes. The probability of an event can be expressed as the number of occurrences of a targeted event divided by the number of occurrences and the number of failures of its occurrence.
