II 81
Variable/mathematics/logic/Frege: variables have nothing to do with change. Arithmetic: arithmetic has nothing to do with quantities like e.g. lengths - only with numbers.
II 83 f
Variable/Frege: a variable is not a name of an "indeterminate" or "variable" number. "X" has no properties (only in context). "Indeterminately": indeterminately is not an adjective but an adverb to the process of the calculation. "Universality": universality is not a meaning but a suggestion.
Letters are rarely names of numbers: e.g. π, i and e are not variables but constants.
>Indeterminacy.
Solution: e.g. "n" is used in the antecedent of a conditional sentence.
II 85
Number/Frege: e.g. "a variable takes a value": here, the number must play both roles: as an object it becomes a variable, as a property it is called value.
>Numbers.
II 87
Variable/designation/description/Frege: "x" designates nothing! X only hints at numbers. Therefore, e.g. "x² + 3x" designates nothing. The whole function only indicates. On the other hand, "sin" (sinus) is a sign that designates. But not a law yet.
Law/Frege: e.g. "y = sin x".
>Denotation.
