|Individual Constants: individual constants are symbols representing a single object, as opposed to individual variables. Individual constants allow you to insert a name for the object when it occurs repeatedly within a formula or an inference. Often, an a, b, c,… is used for individual constants while x, y, z are for individual variables. Individual variables do not ensure that the same object is meant during repeated use. See also constants, variables, logic, interpretation, Substitution._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.
