What is mathematical logic?
Mathematical logic has now taken on a life of its own, and also thrives on many interactions with other areas of mathematics and computer science. In the second half of the last century, logic as pursued by mathematicians gradually branched into four main areas: model theory, computability theory (or recursion theory), set theory, and proof theory.

What are the 4 main areas of logic?
In the second half of the last century, logic as pursued by mathematicians gradually branched into four main areas: model theory, computability theory (or recursion theory), set theory, and proof theory. The topics in this course are part of the common background of mathematicians active in any of these areas.

How do you determine if a formula is a logical consequence?
Use the truth tables method to determine whether the formula'is a logical consequence of the formula : :p. Solution. interpretation satisfyingpsisatisﬁes also'. Exercise 2.7. method to determine whetherp! and:parelogically equivalent. Solution. for every possible interpretation they evaluate to tha same truth value. Exercise 2.8. (p!p)!p p!(p!p)

What are the basic concepts of logic denition?
BASIC CONCEPTS OF LOGIC Denition. We say that Ais a model of or holds in A(denoted Aj= ) if Aj= ˙for each ˙2. To discuss examples it is convenient to introduce some notation. Suppose L contains (at least) the constant symbol 0 and the binary function symbol +. Given any terms t 1;:::;t nwe dene the term t 1+ +t

FIGURE LOGIC by Linda Thistle BEGINNER Solve Figure Logic by completing some simple arithmetic problems, which will enable you to move fromclue to clue through the puzzle. You may discover that, at times, you will not be able to complete anentire number at first, but you may be able, by logic, to determine what one or more of the digits mustbe.

Theorem 1. [(p ) r) ^ (r ) q)] ) [p ) q] Proof. To prove this theorem, we wish to show that the above proposition is always true. Recall that the conditional statement p ) q can be written as :p _ q). Hence, we can rewrite the entire structure above as follows: [(p ) r) ^ (r ) q)] ) [p ) q]
