A Variable is an object with a certain identity, but the environment that surrounds it forces it to vary around the conditions that arise. One of the most common applications of the term is in mathematics, since, when an equation is presented to us, it is in order to give a fixed and exact value to one or more variables, this condition allows the resolution problems are easier. Equations are the simplest ways to operate complex situations mathematically, in which exact amounts must be determined for precise values. Variables are generally the answers given to problems.
From a more social point of view, the term variable corresponds in a certain way as in mathematics, without numbers of course, but variables include each and every one of the situations, circumstances, options and ways of solving a problem. The term comes from the Latin " Variabilis, it refers to" Variety ", with this we emphasize the idea that variables are nothing more than alternatives to take a path, of course, from here the concept is clearly abstract, as it has the ability to adapt to any situation no matter how well versed it may be. In the universe of things, which includes the explanation of each situation in life, it could be said that each variable has an answer, however, this will always be a statement without a clear foundation.
Variables are diversified according to their use, for example, if you have the nominal value for a variable, it is not necessary to search for its value through any function or expression that tells me how to do it. The variables that express a relationship with some characteristics qualify the conditions of something that is always that way, if its behavior or functions are altered, it will become of another quality. Computer science, astronomy, chemistry, physics in any of their names, use the term to refer to changes in the study that is being carried out.
