Class 7 Math Book Chapter 1 rational and irrational numbers
We realize this diversity of varied nature through calculations and numbers. In the previous class, we got ideas about natural numbers, integers, and fractions known as rational numbers. These numbers can be expressed in the ratio of two integers.
There are some numbers in the world of numbers that cannot be expressed in the ratio of two integers. These are known as irrational numbers. In this chapter, we will get acquainted with irrational numbers and discuss their application.
Class 7 Math Book Chapter 2 Proportion and Profit-Loss
We face many problems in our daily life and we can easily solve all these problems using the concept and explanation of proportions. Therefore, it is essential for students to have an idea about proportions and proportions and to acquire the skills to apply them. In this context, the student needs to have a clear knowledge of profit and loss. Therefore, in this chapter, the issues related to proportionality and kick-loss have been presented in detail.
Class 7 Math Book Chapter 3 Measurements
In daily life, we use different types of products including rice, pulses, sugar, salt, fruits, milk, oil, water, etc. These need to be measured in business and practical matters. In the previous class, we got the idea of measuring length, weight, area, and time.
To measure length or distance we compare it to the length of a certain size. Products other than liquids have to be measured by weight. But the liquid has no shape. Measurements of a certain size are used to measure it. This chapter discusses in detail the measurement of length, area, weight, and volume of fluid.
Class 7 Math Book Chapter 4 Multiplication and division
The four basic processes of mathematics are addition, subtraction, multiplication, and division. Subtraction is the opposite process of addition and division is the opposite process of multiplication. Only positively marked numbers are used in arithmetic.
But in algebra, both positive and negative symbols and numerical symbols are also used. We got the idea of addition and subtraction of the sum marked in the sixth grade and addition and subtraction of the algebraic sum. This chapter deals with the multiplication and division of marked sums and the process of multiplication and division of algebraic sums.

Class 7 Math Book Chapter 5 Algebraic formulas and applications
Any general rule or decision expressed by an algebraic symbol is called an algebraic formula or formula for short. We use formulas in different cases. This chapter shows the first four formulas and the method of diagnosing conclusions with the help of these four formulas.
In addition, the application of algebraic formulas and conclusions to determine the value of algebraic quantities and the analysis of the product has been presented. Again, with the help of algebraic sums, the idea of divisors, divisors, multipliers, and multipliers has been given, and how the GCG of the above three algebraic sums has been given. And L.S.G. What can be diagnosed has been discussed.
Class 7 Math Book Chapter 6 Algebraic Fractions
Fraction means broken parts. Amna uses a part of it with a whole thing in daily life. So fractions are an essential part of mathematics. Algebraic fractions play an important role in algebraic fractions as well as in arithmetic fractions. Many complex problems with arithmetic fractions can be easily solved with algebraic fractions. So students need to have a clear idea about algebraic fractions. This chapter presents the reduction of algebraic fractions, common denominators, and addition and subtraction.
Class 7 Math Book Chapter 7 Simple Equations
In sixth grade, we learned what equations and simple equations are and learned to solve them by constructing equations from realistic problems. In this seventh-grade chapter, we will learn about some of the rules of solving equations and their application and learn to solve them by constructing equations based on real problems. In addition, this chapter gives an initial idea about the graph and the solution of the equation is shown in the graph.
Class 7 Math Book Chapter 8 Parallel Straight Lines
Some of the things we see and use around us in our daily lives are square, and someand are round. Our houses, buildings, doors and windows, beds, cupboards, tables, chairs, books, etc. are all square. Considering their edges as straight lines, it can be seen that they are equidistant or parallel.
Class 7 Math Book Chapter 9 Triangle
We know that the boundary of a field bounded by three segments is called a triangle and the segments are called the sides of the triangle. The common point of any two arms is called the vertex. The angle that the two arms produce at the vertex is the angle of the triangle.
The triangle has three arms and three angles. There are three types of triangles in arms: equilateral, equilateral, and equilateral. There are also three types of angles at right angles: right-angled, right-angled, and right-angled.
The sum of the lengths of the three arms of the bridge is called the range of the bridge. In the light of this, other features of triangles and basic theorems and drawings related to triangles have been discussed.
