Syntactic Codes and Grammar Refinement
... start symbol S together with rules S → T for each T ∈ Σ we can reduce the grammar to a cfg with only a single start symbol. Secondly, the terminal symbols correspond more to preterminal symbols in standard cfgs. To get a standard cfg from cfgs as defined here one has to specify a lexicon in addition ...

1 Deductive Reasoning and Logical Connectives
... No matter what number might be chosen, if it is greater than 3, then its square is greater 9. We introduce a variable to replace the words referring to the number: No matter what number n might be chosen, if n is greater than 3, then n2 is greater than 9. If a variable is used to stand for an object ...
