Let’s Be Logical!neralized arithmetic using variables instead of numbers. Similarly, we can build compounded statements from simple statements, and we can study their general structures. The branch of mathematics dealing with the structure of statements is called .. A study of the rules of logic is essential when one studies correct reasoning.

Working in the Fields (and Other Structures)the benefit of abstracting the common properties of various systems into a unifying structure is that, once we prove certain statements about a structure using only the properties that apply to all models of the structure, they will then be true for each system that models the structure. In this chapter we see examples for such ..

What’s the Name of the Game? have a precise and consistent meaning, and its results, once established, are not subject to opinions or experimental verification and remain valid independently of time, place, and culture—although their perceived importance might vary. In this chapter we discuss mathematical concepts; in Chap. 3

Existential Proofs the form . For instance, we may claim that a certain equation has a real number solution (the existence of ., to be formally proven only in ., is a prime example), or we may claim that a certain set has a minimum element (by Theorem 13.6, every nonempty set of natural numbers does). Quite often, we
