CHAPTER 1. SENTENTIAL LOGIC 1. Introduction In sentential logic
... The truth value of any compound sentence is determined completely by the truth values of its component parts. For example, assuming 2, 7, odd, prime all have their usual meanings then 7 is odd and 2 is odd is false but (7 is odd and 2 is odd) or 2 is prime is true. We will discuss implication later. ...

... For two integers a and b 6= 0, there may exist an integer q such that a = bq. If this happens, then we say that b divides a, and denote this fact by writing b|a. If b|a, then a is called a multiple of b, b is called a divisor of a and q is called the quotient of the division of a by b. Using “the” i ...

LINEAR LOGIC AS A FRAMEWORK FOR SPECIFYING SEQUENT

By making use of classical linear logic, we are able to capture not only natural deduction proof systems but also many sequent calculus proof systems. We will ...

Mathematical proof

In mathematics, a proof is a deductive argument for a mathematical statement. In the argument, other previously established statements, such as theorems, can be used. In principle, a proof can be traced back to self-evident or assumed statements, known as axioms. Proofs are examples of deductive reasoning and are distinguished from inductive or empirical arguments; a proof must demonstrate that a statement is always true (occasionally by listing all possible cases and showing that it holds in each), rather than enumerate many confirmatory cases. An unproved proposition that is believed true is known as a conjecture.Proofs employ logic but usually include some amount of natural language which usually admits some ambiguity. In fact, the vast majority of proofs in written mathematics can be considered as applications of rigorous informal logic. Purely formal proofs, written in symbolic language instead of natural language, are considered in proof theory. The distinction between formal and informal proofs has led to much examination of current and historical mathematical practice, quasi-empiricism in mathematics, and so-called folk mathematics (in both senses of that term). The philosophy of mathematics is concerned with the role of language and logic in proofs, and mathematics as a language.
