Value
Value In math, value is a number signifying the result of a calculation or function. Examples: The value of 4 x 6 is 24 The value of x + y if x = 6 and y = 3 is 9. y=2x + 3, the value of y if x = 4 is 11 ( y = 2 · […]
Numerator
Numerator Numerator is the part of a fraction that is above the line and signifies the number of parts selected or removed from the total number to be divided by the denominator. […]
Number
Number Number is a unit or a symbol that forms part of a system of counting and calculating, and that represents an amount or position in a series. The most basic examples are the natural numbers 1, 2, 3, 4, 5, 6, 7, 9, 10, 11……and so on. In mathematics, the notion of number has been extended over […]
Obtuse triangle
Obtuse triangle An obtuse triangle or obtuse-angled triangle is a type of triangle that has one obtuse (greater than 90°) angle. As the sum of all the interior angles of a triangle is 180°, an obtuse-angled triangle has one obtuse angle and two acute angles (less than 90° each). An obtuse triangle is like this: […]
Negative number
Negative number A negative number is a number whose value is always less than zero and it has a minus (-) sign before it. On a number line, negative numbers are represented on the left side of zero. They can be integers, decimals, or fractions. For example: -7, -24, -3/5, -0.8 are termed as negative numbers. Here […]
Negative integer
Negative integer A negative integer is the opposite of a natural number. It is not a fraction or a decimal. It is a number whose value is always less than zero and it has a minus (-) sign before it. For example, -3 and -5 are negative integers. On a number line, negative numbers are represented on the […]
Incircle, incentre, inradius
Incircle, incentre, inradius -An incircle is a closed plane curve whose points are equidistant from another point located inside it, called centre. -An incentre is the point from which all points are equidistant. -An inradius is a linear segment joining any point on the circumference or the surface of a sphere with its centre.

Integer
Integer Integers can be positive, negative, or zero. They are used to count things, measure distances, and represent quantities. Integers are also used in many mathematical formulas and equations. Here are some examples of integers: 1, 2, 3, 4, 5, … (positive integers) -1, -2, -3, -4, -5, … (negative integers) 0 (zero) Integers can […]
Distance
Distance Distance between two points is the length of the line segment that connects the two points in a plane. A._______________________________________________________.B The distance between point and line is the shortest distance between the point and a point on the line. The distance of a point from a line is the perpendicular line from the point to […]
