Binomials theory
POLYNOMIALS: Binomials Binomials are polynomials consist of two monomials separated by a plus (+) or a minus (-) sign. Binomials operations are: 1.- Binomial squared: is equal to the square of the […]
Variations theory
Variations Variations is to group elements, when it matters the order, we do not take all the items and these can be repeated or not. Thus the variations may be: Variations without repetition […]
Permutations Theory
Permutations Permutations are multiplicative events where the number of possibilities is decreasing and whether it is important the order of a permutation, it is an arrangement of a set of objects in a defined […]
Divisibility theory
Divisibility Divisibility is the property of an integer number to be divided by another, resulting an integer number. Where a and b, two integers numbers, we will say that “a” is a multiple of […]
Combined Operations theory
Combined Operations We call Combined Operations to those in which several arithmetic operations appear to be solved. To get the right result you need to follow some rules and take into account the priority […]
Radicals theory
Radicals Radicals are expressions with the form: Where n Є N and a Є R; provided that when a is negative, n must be odd. n=index; a=radicand; m=exponent. A radical can be expressed […]
