When we multiply a number continuously by itself till a certain number, then exponents are used to writing these numbers in a suitable and convenient form. In mathematics, we use different laws of exponents to solve large calculations. In this section, we will study different laws of exponents for real numbers. Before understanding the laws …
In this section, we shall study different mathematical operations on real numbers such as addition, subtraction, multiplication, and division. We know that rational numbers and irrational numbers are real numbers so weтАЩll apply operations on them. For Rational Numbers As we have learnt in previous classes, rational numbers satisfy the commutative, associative, and distributive properties …
As per the knowledge of the previous classes, we are familiar with the representation of different types of numbers on the number line like the representation of natural numbers, whole numbers, integers, and rational numbers. In this section, weтАЩll learn the representation of real numbers on the number line including irrational numbers also. WeтАЩll represent …

As we know that collections of all rational numbers and irrational numbers are known as real numbers. In this section, we shall study decimal expansions of real numbers means decimal expansions of rational numbers and irrational numbers. First, we start with rational numbers. Decimal Expansions of Rational Numbers Rational numbers are in the form of …
In the previous classes, we studied the number system. We know the types of numbers, number lines, and how to represent different types of numbers on the number line. We have studied natural numbers, whole numbers, integers, rational numbers, etc. In class 9th, we will study more about the number system but before it let …
Introduction In geometry, we know that a square is a figure enclosed by four equal line segments and the area of the square is given by side├Чside (where тАШsideтАЩ indicates the length of each side of the square). Similarly, in the number system, we find the square of the numbers with the help of this …
Introduction We have studied natural numbers, whole numbers, and integers in the previous class. We know that the collection of all the positive and negative numbers along 0 are called integers. We can also say that integers are the set of whole numbers and negative numbers. In class 7th, we will study more about integers …
Introduction In the previous class, we have already studied powers and exponents. We know that exponents are used to writing large numbers in a suitable and convenient form. In large calculations, powers and exponents are very important and useful. In class 8th, we shall explore more about powers and exponents with the help of its …
Introduction In the number system, we have already studied whole numbers, natural numbers, integers, fractions, decimal numbers, etc. All of these types of numbers have different properties. In class 8th, we shall study Rational numbers, their definition, and properties, the representation of rational numbers on the number lines, etc. Definition of Rational Number A number …
Introduction As the name suggests, these numbers are real for mathematical calculations. There are different types of real numbers. In class 8th, we will get into the definition, types with examples, and properties of Real Numbers. Definition All the rational numbers and irrational numbers are called Real Numbers. Real numbers are denoted by R. Examples …
