Chapter 6: Integers

The collection of numbers 0, +1, –1, +2, –2, +3, –3, …… is called integers. The numbers +1, +2, +3, +4, ….. are referred to as positive integers. The numbers –1, –2, –3, –4, ……. are referred to as negative integers. The numbers 0, +1, +2, +3, …… are called non-negative integers. All the positive integers lie to the right of 0 and the negative integers to the left of 0 on the number line. All non negative integers are the same as whole numbers and hence all the operations on them are done….…. READMORE

Chapter 7: Fractions

A fraction is a number representing a part of a whole. This whole may be a single object or a group of objects. A fraction whose numerator is less than the denominator is called a proper fraction, otherwise it is called an  improper fraction. Numbers of the type 541 3 ,8….…. READMORE

Chapter 10: Mensuration

Perimeter of a closed figure is the distance covered in one round along the boundary of the figure.  A closed figure in which all sides and angles are equal is called a regular polygon.  Perimeter of a rectangle = 2 × (length + breadth) Perimeter of a square ….…. READMORE

Chapter 11: Algebra

The word ‘variable’ means something that can vary, i.e., change. The value of a variable is not fixed. We use a variable to represent a number and denote it by any letter such as l, m, n, p, x, y, z etc. A variable allows us to express relation in any practical situation ….…. READMORE

Chapter 12: Ratio and Proportion

Ratio, Proportion and Unitary Method.  The comparison of two numbers or quantities by division is known as the ratio. Symbol ‘:’ is used to denote ratio. For a ratio, the two quantities must be in the same unit. If they are not, they should be expressed in the ….…. READMORE

Chapter 13: Symmetry

A figure is said to have line symmetry, if by folding the figure along a line, the left and right parts of it coincide exactly.  The line is called the line (or axis) of symmetry of the figure. A figure may……….. READ MORE

Chapter 14: Practical Geometry

A figure is said to have line symmetry, if by folding the figure along a line, the left and right parts of it coincide exactly. The line is called the line (or axis) of symmetry of the figure. A figure may have no line of symmetry, one line of symmetry, two lines of symmetry….…. READMORE
