... that every time we add two odd integers, the sum is an even integer. However, it is not possible to test every pair of odd integers, and so we can only say that the conjecture appears to be true. (We will prove that this statement is true in the next section.) Use of prior knowledge. This also is ...

... the study of predicativity given the natural numbers. There would be no difficulty in working with an ordering < of the natural numbers that is quite simple, say Δ0, to represent the ordinal levels. Then we would index levels by numbers preceding in the ordering a certain number n, where transfinite ...

On simultaneous rational approximation to a real
... Theorem 1 is a new contribution towards the resolution of the Main Problem investigated in [6]. It improves Theorem 7.7 from [6], where (2.1) is replaced by the inequality (w + 1 − m)(w + 1 − m − k) ≥ m(m + k)(w + 1). The key idea, which goes back to Güting [12], is to construct suitable real numbe ...

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.
