The symbol that appears in propositions, algorithms, formulas and functions and that takes different values ​​is called a variable . According to their characteristics, it is possible to distinguish between different classes of variables. The quantitative variables are those that adopt numerical values (ie, numbers). In this way they differ from qualitative variables , which express qualities, attributes, categories or characteristics. It is important at this point that we proceed to know the etymological origin of the two words that give shape to the term that concerns us: -Variable comes from Latin, specifically derived from "variabilis", which can be translated as "that can change its appearance" . It is the result of the sum of two components: the verb "variare", which is synonymous with "change of appearance", and the suffix "-able", which is used to indicate possibility. -Quantitative, for its part, comes from Latin as we...

A variable , in the field of mathematics , is a symbol that can appear in a function, an algorithm, a proposition or a formula, adopting different values . By establishing links with other variables, they can contribute to the development of a theory or a hypothesis, acquiring the name of constructs . It is possible to differentiate between different classes of variables depending on the context. The qualitative variables are those that allow expression of a property , one category , one attribute or attribute . It is interesting in this sense to know the etymological origin of the two words that make up the term at hand. Thus, we can establish the following information: -Variable comes from Latin, specifically from “variabilis” which is the result of the sum of two components: the verb “variare”, which can be translated as “change of appearance”, and the suffix “- able ”, which is used to indicate possibility. -Qualitative, on the other hand, also derives from Latin.
