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 →Variable – Definition and Example Definition: Variables are symbol or letters that used to represent for unknown numbers or values. simply a single letter, that represents a number called the value of the variable. m + n, here m and n are variables. 3x + y = 12, here x and […]
Read More →Factor – Definition and Examples Definition: A number break up into another numbers that can be multiplied together and get original number. or A number that divides into another number exactly and without leaving a remainder is a Factor. or A factor is a number that is divisible by another number and the quotient […]
Read More →Co – Prime Numbers What are Co-prime Numbers? The pairs of numbers that do not have any common factor other than one are co-prime numbers. Let a and b are two positive integers are called co-prime numbers, if the only one 1 as their common factor. (a, b) is said to be a co-prime pair. […]
Read More →Type of Polygons Definition A polygon is a two-dimensional shape form with more than three straight lines. In a polygon each side must be intersect exactly two other sides, but only at their end points and have a common endpoint. The sides have must noncollinear. The name of a polygon usually depends on how […]
Read More →Complement of a Set Definition: The complement of a set A, is set of all elements of universal set, which are not the elements of A. Let U be the Universal set and A is subset of U, then the “Complement of A” is set of all elements of U which are not the elements of A. […]
Read More →Prime numbers – Composite numbers What are prime numbers? What are composite numbers? Here we will learn more about, how to classify these numbers and also answers of some common questions about prime numbers and composite numbers. Definition: Prime numbers A prime number is a natural number, greater than 1 with exactly two factors. A prime number […]
Read More →Grouping of Data In this lesson we will learn about the grouping of data. Grouped data are data that has been organized in groups known as classes. Grouped data has been classified and a data class is group of data. Consider the marks obtain by 15 students in a history test as given below, 23, […]
Read More →Median – Definition Median is the middle value of a given distribution or group of numbers in their ascending order. OR in simplest way, we can say that the median is the midpoint of the given set of data. Median = Middle number Example: If we have numbers like 1, 2, 3, 4, 5. The […]
Read More →Angle Bisector – Definition -Examples The angle(interior) bisector of an angle is a line or line segment that divides the angle into two (congruent)equal parts. The angle bisector is also called the internal angle bisector. In ∠ABC, BD is angle bisector of ∠ABC. In above figure BD is bisect the ∠ABC. ∵ ∠ABC = 900∴ ∠ABD = 450and ∠DBC = 450 ∠ABD and ∠DBC […]
