Representation of integers on the number line and their addition and subtraction Product of a positive integer and a negative integer is a negative integer, i.e, a × (–b) = – ab, where a and b are positive integers. Product of two negative integers is a positive integer, i.e., (–a) × (–b) = ab, where a and b are positive integers. Product of even number of negative integers is positive, where as the product of ……….

A fraction is either a proper fraction or an improper fraction.  A proper fraction is a number representing a part of a whole. This  whole may be a single object or a group of objects. An improper fraction is a number in which numerator is greater than denominator. A mixed fraction is a combination of  ……….

The information collected in the form of numbers is called Data. Data is organised and represented graphically so that it becomes easy to understand and interpret. The difference between the highest and lowest observations in a given data is called its Range. The average ………….. READ MORE

The word variable means something that can vary i.e., change and constant means that does not vary. The value of a variable is not fixed. Variables are denoted usually by letters of the English alphabets such as x, y, z, l, m, n, p, a etc.
The expressions are formed by performing operations like ………. READ MORE

An angle is formed when two lines or rays or line segments meet or intersect. When the sum of the measures of two angles is 90°, the angles are called complementary angles. Each of them is called complement of the other. When the sum of the measures of two angles is………… READ MORE

The six elements of a triangle are its three angles and the three sides. The line segment joining a vertex of a triangle to the mid point of its opposite side is called a median of the triangle. A triangle has 3 medians. The perpendicular line segment from a vertex of a triangle……….. READ MORE

To compare two quantities, their units must be the same. Two ratios can be compared by converting them into like fractions. If the two fractions are equal, ………READ MORE

A number that can be expressed in the form p / q , where p and q are integers and q ≠ 0, is called a rational number.
All integers and fractions are rational numbers. If the numerator and denominator of a rational number are multiplied or divided by a non-zero integer, we get a rational number which is said………READ MORE

Let a line ‘l’ and a point P not lying on it be given. By using properties of a transversal and parallel lines, a line which passes through the point P and parallel to ‘l’, can be drawn. A triangle can be drawn if an……...READ MORE

Perimeter of a closed figure is the distance around it while area is the measure of the part of plane or region enclosed by it. Perimeter of a regular polygon = Number of sides × Length of one side. Perimeter  ………READ MORE

Algebraic expression is formed from variables and constants using different operations. Expressions are made up of terms. A term is the product of factors. Factors may be numerica………READ MORE

Exponents are used to express large numbers in shorter form to make them easy to read, understand, compare and operate upon. a × a × a × a = a4 (read as ‘a’ raised to the exponent 4 or the fourth power of a), where ‘a’ is the base and 4 is the exponent and a4 is called the exponential………READ MORE
