Squares and odd numbers The series of first n odd square numbers are 1, 9, 25, 49, 81, 121…… When we add, odd numbers we get square numbers. 1. First odd number is 1, and square of 1 is (1 x 1 = 1) 2. Next odd number is 3, total of 1 and […]
Read More →Order of mathematical Operations The four basic operation in mathematics, as everyone knows, are addition, subtraction, multiplication and division. These basic operations are used in algebra with numbers or letters or combination of both. A number multiplied by a variable, a number or variable is called a term. An expression is combination of such terms. Example: In […]
Read More →Method of completing the square Below are steps to solve the quadratic equation by Completing Square. (1) First we set given equation all terms of the equation on one side, of equal sign and other side leaving zero. (2) Factor the non zero side. (3) Set each factor equal to zero. (4) Solve each of […]
Read More →Converse of Pythagorean Theorem In this section we are going to see the converse of Pythagorean theorem. We know the Pythagorean theorem applies to right triangles and states that, The square of the length of the hypotenuse, equals the sum of the squares of the lengths of the other two sides. (hypotenuse)2 = (Base)2+(Perpendicular)2 […]

Diagonals of Polygon’s A polygon’s diagonal’s are line segments, that joining from one corner to another corner. Formula for number of diagonals = n(n-3)/2 where n is number of sides or […]

In the below figure if we start measure from the point A and move along the line segments and reach again the point A.We have […]

Read More →Square Root of a Number The inverse (opposite) operation of addition is subtraction and the inverse operation of multiplication is division. Similarly, The “square root” is the inverse operation of squaring that number. Square root of a number is number itself. Square of 1 = 1 x 1 = 1 = 12 […]
