SELINA Solutions for Class 8 Maths ICSE

An overview of what each chapter encompasses helps you understand what and why you will be dealing with it. So here is it. 

Chapter 1: Rational Numbers 

The solutions here can be found for arithmetic operations of rational numbers. It also solves the problems of the insertion of rational numbers between the given rational numbers, finding comparative large numbers and problems of rational numbers on a line. 

Chapter 2: Exponents (Powers)

Exponents/Powers chapters include concepts and laws of exponents. Besides more solutions related to the concept, the answers are also present for negative, integral exponents. 

Chapter 3: Squares and Square Roots 

Here, you will learn the concept of square roots. Thus, the solution will be given to finding square roots through different methods like the division method and prime factorisation. The assistance will also be for the utilisation of the properties of square numbers and finding the square root of a number that isn’t a perfect square itself. 

Chapter 4: Cubes and Cube Roots 

Similar to the previous chapter, this one includes an introduction to the concept of cube root. Hence, the problems will be solely based on cube root calculation through multiple methods. 

Chapter 5: Playing with Numbers 

It is an interesting part of SELINA Maths 8, where students get well-versed in the arrangement of objects in rows and columns. They also gain practice on divisibility by 2, 3, 4, 5, 6, 10 and 11. It also includes cryptarithm, its properties and the generalised form of numbers. 

Chapter 6: Sets 

Solutions to problems based on a cardinal number of sets, components, differences and associated laws will be depicted here in a stepwise manner. Further, the constituents will also be subsets, set representations, operations and Venn diagrams. It will also include different types of sets. 

Chapter 7: Percent and Percentages 

The chapter comprises solutions to problems of percent and percentages. You will find different approaches to reach the answer based on the type of problem. 

Chapter 8: Profit, Loss and Discount (Including Overhead Expenses and Tax) 

You can assess your understanding and ability to solve problems related to profit, loss, and discount. The chapter will include solutions to tax computation, Goods and Service Tax (GST), overhead expenses, and problems related to CP, SP and others. 

Chapter 9: Interest (Simple and Compound) 

Enhance your concept clarity of simple and compound interest with this chapter. Dive into principal, interest rate and time of interest, such as yearly and half-yearly. 

Chapter 10: Direct and Inverse Variations (Including Time and Work) 

The solutions here are for the concept of unitary method, arrow method, direct and inverse variation and time and work. 

Chapter 11: Algebraic Expressions (Including Operations on Algebraic Expressions)

The algebra solutions can now be easily solved with expert-curated answers. The components of the chapter are a combination of terms and associated problems, such as monomial by monomial division and polynomial by monomial and polynomial division. It also provides solutions to different mathematical operations related to polynomials and like and unlike terms. Additionally, find the solutions to questions on product, factor, and coefficient and simplification of expressions here. 

Chapter 12: Identities 

Find stepwise solutions to algebraic identities, formula-based questions, binomial cubes, and the expansion form of numbers. It also includes the product of sums and the difference between two numbers. 

Chapter 13: Factorisation 

With factorisation, you will become proficient in solving questions using different methods. The approaches included here are multiple, consisting of two squares, grouping, common factors, and trinomials. 

Chapter 14: Linear Equations in One Variable (With Problems Based on Linear Equations) 

The linear equations are divided into two parts in SELINA Concise Mathematics Class 8. This part focuses on one variable, and hence, you will find solutions to equations reducible to linear form and simple linear equations.

Chapter 15: Linear Inequations (Including Number Lines) 

The other part includes linear equations in two variables, operation of whole numbers on a number line and solution and replacement set. 

Chapter 16: Understanding Shapes (Including Polygons) 

This chapter will help you to skill up in understanding the details of shapes like polygons and quadrilaterals. The solutions to be found here are for adjacent and opposite sides and angles. It also includes different types of curves, such as closed, open and simple curves. Further, the problems solved here are for regular polynomials and their sum of interior and exterior angles. 

Chapter 17: Special Types of Quadrilaterals 

You will learn the different approaches to solving questions on parallelograms and the utilisation of properties of shapes like rhombus, rectangle and trapezium. Solutions to diagonal-based questions are also available in this chapter. 

Chapter 18: Constructions (Using ruler and compasses only) 

Dive into the exciting part of SELINA Maths Class 8, i.e., geometry. Make different angles, line bisectors, parallel lines and shapes using a ruler and compass and validate your answers at TopperLearning’s SELINA Maths Class 8 Solutions. The answers for angle bisector, angle construction, perpendicular line construction, and more are also given. 

Chapter 19: Representing 3-D in 2-D

This chapter in SELINA Class 8 Maths Solution offers a 2D perspective towards 3D objects. You will be introduced to and evaluated on the concept of polyhedron, the application of Euler’s formula and nets for building 3D shapes. Faces, vertices and edges are also solved here. 

Chapter 20: Symmetry (Including Reflection and Rotation) 

This part in Maths Concise Class 8 is based on reflection and rotation of symmetry. Find the solutions to all the related concepts here while knowing their importance in real life. The solutions are, like others, created by academicians with years of experience in the teaching industry. 

Chapter 21: Area of a Trapezium and a Polygon 

Do you know the formula for the area of a trapezium, parallelogram, rhombus, circle, and the perimeter of a square, triangle, and rectangle? If yes, you are at the right place to practise your hands and mind to solve the related problems. If not, introduce yourself to simple formulas and become an expert in calculation with SELINA Class 8 Maths Solution. 

Chapter 22: Surface Area, Volume and Capacity (Cuboid, Cube and Cylinder) 

Continuing the education on formula, SELINA Concise Maths Class 8 brings with this chapter the surface area, volume and capacity problems. These are for the shapes cube, cuboid and cylinder. Get different approaches to solve while cross-checking the accuracy of your approach. 

Chapter 23: Data Handling 

Since the world is progressing and relying on data, it is essential to teach the concept. Hence, you can become well-practised in calculating frequency and constructing frequency tables and graphical representations of data. You will also encounter solutions to problems on arrayed data. 

Chapter 24: Probability 

This chapter is a small introduction to a vast topic: probability. The SELINA Maths 8 helps students get familiar with basic concepts, terms and calculations in probability.
