mathematical logic examples

in mathematical logic we formalize (formulate in a precise mathematical way) notions used informally by mathematicians such as: property statement (in a given language) structure truth (what it means for a given statement to be true in a given structure) proof (from a given set of axioms) algorithm 1In the case of set theory one could dispute this. Mathematical Logic 2. The rules of logic give precise meaning to mathematical statements. So, it is natural that every science which uses the definite numbers and statistical methods of the research has to rely on the mathematical models who help them organize the results of the analysis wisely and logically.
