On 12 April 2018, the police said that Rakesh Kumar, who leaked the class 12 economics paper, had leaked class 10 mathematics paper also. [40] Consequently, the Central Board of Secondary Education has put in place a system of "encrypted" question papers, which are supposed to be printed by the schools half an hour before the exam starts. [41]
The term finite mathematics is sometimes applied to parts of the field of discrete mathematics that deals with finite sets, particularly those areas relevant to business. Research in discrete mathematics increased in the latter half of the twentieth century partly due to the development of digital computers which operate in "discrete" steps and ...
In Bangladesh, students attend primary schools for six years. Primary/secondary education in Bangladesh is segregated as Primary (Pre school 1 Year + Class 1 -5), Junior High School (Class 6 - Class-10) and Higher Secondary or intermediate (11th and 12th Class) are as follows : Preschool: 5 years.-6 years. (optional) Class 1: 6-7; Class 2: 7-8
In mathematics, Pascal's triangle is an infinite triangular array of the binomial coefficients which play a crucial role in probability theory, combinatorics, and algebra.In much of the Western world, it is named after the French mathematician Blaise Pascal, although other mathematicians studied it centuries before him in Persia, [1] India, [2] China, Germany, and Italy.
In modern mathematics, there are many similar situations in which understanding a problem requires studying certain permutations related to it. The study of permutations as substitutions on n elements led to the notion of group as algebraic structure, through the works of Cauchy (1815 memoir).
The area of a Pythagorean triangle cannot be the square [12]: p. 17 or twice the square [12]: p. 21 of an integer. Exactly one of a, b is divisible by 2 (is even), and the hypotenuse c is always odd. [13] Exactly one of a, b is divisible by 3, but never c. [14] [8]: 23–25
A set of polygons in an Euler diagram This set equals the one depicted above since both have the very same elements.. In mathematics, a set is a collection of different [1] things; [2] [3] [4] these things are called elements or members of the set and are typically mathematical objects of any kind: numbers, symbols, points in space, lines, other geometrical shapes, variables, or even other ...
In elementary algebra, the binomial theorem (or binomial expansion) describes the algebraic expansion of powers of a binomial.According to the theorem, the power (+) expands into a polynomial with terms of the form , where the exponents and are nonnegative integers satisfying + = and the coefficient of each term is a specific positive integer ...
