Aug 19, 2016 · If just the difference between two numbers want to be observed, then you should get the positive value and define the difference between two numbers as the absolute value of their difference, obtaining always the positive value. In the -5 and 2 example the difference would be $|-5-2|=|2- (-5)|=7$.

11 There is no difference between the two. But, "set" has been the word that mathematicians have elected among its synonyms to describe the mathematical entity of a set/collection, as formalised in Zermelo-Fraenkel set theory. This entity can be used (in theory) to give a formal description of all of mathematics in the "language of sets".
