Although they can be written in a completely symbolic form, for example, within the propositional calculus, theorems are often expressed in a natural language such as English.
36.
In recognition of this problem, the sign ?! of formal implication in the propositional calculus is called material implication to distinguish it from the everyday, intuitive implication.
37.
In a typical argument, quantifiers are eliminated, then propositional calculus is applied to unquantified expressions ( which typically contain free variables ), and then the quantifiers are reintroduced.
38.
In propositional calculus, a "'syncategorematic term "'is a term that has no individual meaning ( a term with an individual meaning is called categorematic ).

In the following example of a propositional calculus, the transformation rules are intended to be interpreted as the inference rules of a so-called " natural deduction system ".

As noted above, Tarski considers IDENTITY to lie outside the propositional calculus, but he asserts that without the notion, " logic " is insufficient for mathematics and the deductive sciences.
