###### Chapter 1 Number System

This chapter discusses a variety of topics, including rational numbers and irrational numbers. Students will also learn an expanded version of the number line and how the numbers on it (integers, rational and irrational) are represented. There are a total of 6 exercises in this chapter, which cover issues based on all the topics asked in the chapter. This chapter teaches students the representation of the square root of 2 and 3 and other irrational numbers in the term line, as well as the end / end recursive decimal (and the sequential magnification method). The chapter also deals with the laws of integral forces and rational exponents with positive real bases in number systems.

###### Chapter 2 Polynomials

This chapter discusses a particular algebraic expression called polynomial and its related terminology. A polynomial is an expression consisting of variables and coefficients, including addition, subtraction, multiplication, and non-negative integers. The chapter also describes the use of these theories in the rationalization of polynomials with reminder theory and factor theory. Students are taught many examples and definitions of polynomial, degrees, multiples, zeros and polynomial terms. This chapter has a total of 5 exercises, including issues related to all the topics mentioned in the chapter.

###### Chapter 3 Coordinate Geometry

Chapter on Coordinate Geometry The coordinates of a point on a Cartesian plane, xy - points related to the plane, positions, coordinate plane, xx, y-axis, x-coordinate, y-coordinate, basic quadrilateral and much more. In this chapter, students also study the concepts of abscissa and plat and name a point on the xy-plane along with the directors of a point. Exercises 3 in this chapter revolve around the topics mentioned in the chapter, which helps students to fully engage with the concepts.

###### Chapter 4 Linear Equations in Two Variables

In addition to memorizing the knowledge of linear equations on a variable, this chapter introduces students to linear equations in two variables, namely ax + by + c = 0. Students will also learn to draw a graph of a linear equation. Variable. Exercises 4 in this chapter include finding solutions to the linear equation, creating a linear equation in a graph, and other topics discussed in the chapter.

###### Chapter 5 Introduction to Euclids Geometry

This chapter discusses Euclid's approach to geometry and tries to integrate it with current geometry. Euclid's Introduction to Geometry provides students with a method for defining simple geometric shapes and conditions. With the two exercises in the chapter, students take in depth the topic of theories, postulates and theories.

###### Chapter 6 Lines and Angles

This chapter revolves around theories on the subject of lines and angles. Students are often asked to prove the statements given in the questions. There are 3 exercises in solving the chapter, which will help students better understand the topics in the chapter. The chapter has four theories and eight theories.

###### Chapter 7 Triangles

In this lesson, students will study in detail the similarities of triangles, laws of similarity, some properties of triangles, and irregularities in triangles. The chapter has a total of 5 exercises in which students are told "proof-it" as well as application-level problems. With this lesson, students will also learn to prove the characteristics they have learned in previous classes. This chapter teaches students to apply different compliment rules when solving problems. There are about eight theories in this chapter.

###### Chapter 8 Quadrilaterals

The figure obtained by connecting four points in sequence is called a quadrilateral. This chapter takes students to the depths of the quadrilateral. Chapter 2 consists of exercises in which only one theory is proven. However, all nine theories are useful in addressing questions asked at the application or conceptual level. The characteristics of a quadrilateral, the quadrilateral, the properties of a parallelogram, and the angle of midpoint theory are described in this chapter, to help students learn concepts better.

###### Chapter 9 Areas of Parallelograms and Triangles

In this chapter, an attempt is made to consolidate knowledge about formulas to find the areas of different elements, by studying the relationship between the areas of geometric figures, if they exist on the same basis and between similarities. They tell lies. The study is also useful in understanding some of the results on 'equality of triangles'. There are 4 exercises in the chapter, most of which ask students to prove a given statement.

###### Chapter 10 Circles

A circle can be defined as a collection of all the points on the plane, at a fixed distance from a fixed point on the plane. In this chapter there are elements such as the angles of the rag at one point, the uniform beams and their distance from the center, the angles obstructed by the arc of the circle, the cyclic quadrilateral, and other terms relating to the circle. This chapter contains a total of twelve theories that will give students a clear idea of what they are learning through learning. There are 6 exercises in this chapter that cover all the conceptual questions in the chapter.

###### Chapter 11 Constructions

In this lesson, students will learn some basic structures. The learned method is used to construct certain types of triangles. There are 2 exercises in this chapter, the first of which is the construction of a fixed angle or a binomial of a given angle. On the other hand, the second practice concerns the construction of triangles when given different parameters.

###### Chapter 12 Heron’s Formula

This chapter discusses the principle of Heron, which is used to calculate the area of a triangle with respect to the length of the three sides. In this method, there is no need to calculate angles or other distances in the triangle. This formula can be found not only by finding the area of the triangle, but also by dividing the area of the quadrilateral and other polygons into triangles. Exercises 2 in this chapter help students understand the problem solving method based on the Heron principle.

###### Chapter 13 Surface Areas and Volumes

In this lesson, students will learn how to find the size of cubes and surface areas and cylinders with detail, and expand the study with some other solids such as cones and spheres. This chapter is an extended version of the chapter in which students learn about past areas and volumes in alumni classrooms. There are 8 exercises in this chapter, and these exercises are based on surface areas and various solids such as cubes, cuboids, spheres, cylinders, cones, and hemispheres.

###### Chapter 14 Statistics

The branch of mathematics where the extraction of meaningful information is studied is called statistics. It can also be defined as a collection of information on various aspects of the life of the people that serve the state. The chapter teaches about the diverse presentation of data, including frequency distribution. This chapter helps students understand the graphical representation of data using various graphs such as bar graphs, histograms, and frequency polygons. This chapter helps students to understand the central tendency of raw data, average, and mode. There are 4 exercises in the chapter that address these concepts.

###### Chapter 15 Probability

The event of the experiment is called the collection of some of the results of the experiment. The probability that an event will occur is called probability. In this lesson, students learn how to measure the occurrence of a particular outcome in an experiment. There is only 1 exercise in this chapter. The problems in this exercise are based on real-life events, which can increase students' interest in solving questions.
