Full Idea
For the internal question like 'is there a prime number greater than a hundred?' the answers are found by logical analysis based on the rules for the new expressions. The answers here are analytic, i.e., logically true.
Clarification
See Idea 13933 for 'internal' questions
Gist of Idea
Questions about numbers are answered by analysis, and are analytic, and hence logically true
