A permutation of a set is defined for finite sets only. A permutation of a finite set is a bijective relation from itself to itself. A bijective relation refers to one-one mapping. If the cardinal number (the total number of elements in a set) of a finite set is n, then n is also called […]

The percentage is a Latin word that means “out of a hundred”. Percentages always describe a part of a whole, like in fractions or decimals, or parts. The percentage is considering anything as a hundred parts making a whole and describing a certain part out of it. It is denoted using the % symbol.  Percentages

Every Alphabet series has a different concept to “form a sequence” with a definite rule. “Most of the time”, the alphabet sequence or series will ask to find the missing alphabet that can form a sequence. “Circular arrangement series” is also a form of the alphabet series like finding the missing numbers. Five types of

In this case, the field of Mathematics has led to the establishment of alpha-numeric series in the spheres related to the development of computer applications. The subject’s developments had been based on the establishment of compositions in this regard. The development of the alpha-numeric series has been significant as it enables the proper working of

Algebraic Expressions are used to calculate answers for any Mathematical operations involving variables, such as addition, subtraction, multiplication, and division.  In the principles of Algebra, any unknown value is represented by the letters x,y, and z. Variables are the letters that make up the alphabet.  Variables and constants can both be found in an algebraic

Introduction Algebraic expressions are the inferred short formulas that help to settle the conditions without any problem. They are only an improvement of the provided terms to make a superior articulation that is not difficult to retain. The algebraic characters are the mathematical condition, which is legitimate for every one of the factors’ qualities. Arithmetical

The age-related problem in mathematics started in ancient times. The educational structure allows the students to learn the basic formulas to solve age-related mathematical problems. However, with time and up-gradation of classes, the problems become more complex and so do the problem-solving formulas. In the government exams, different types of age-related questions are asked in

To find out the algebraic expression it collects the like terms to add them. the sum of several like the term is the coefficient of the like term. There are mainly two methods of solving additional algebraic expressions : the horizontal method and the column method. The horizontal method is the technique that expresses that

Simplification means determining the solution by reducing or simplifying it from the complex calculation. Simplification helps to reduce a fraction by cancelling it to the lowest common factor(LCM) for both the numerator and the denominator to its lowest term. It also helps to reduce an algebraic expression by grouping and combining similar terms. Simplifying makes

All the competitive exams always have questions from boat and stream topics. In almost all government exams, one will always find 2-3 questions related to this topic. Boat and stream sums are related to speed, distance, and time.  Concept of Boat and Stream Before understanding the concept, remember that the topic deals with a stream
