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×side (where ‘side’ 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 In the previous class, we have already studied powers and exponents. We know that exponents are used to write 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 their …
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 rational numbers and irrational numbers are called Real Numbers. Real numbers are denoted by R. Examples – …
