WebMay 28, 2004 · Some mathematical theories can be finitely axiomatized in a first-order language, but certain historically important number theories and set theories cannot. The axioms of these theories can sometimes be specified using schemata. For example, in first-order number theory the induction principle is specified using the schema WebOct 4, 2013 · Within the history of mathematics, the history of number theory is dedicated to the origins and subsequent developments of number theory (called, in some historical and current contexts, (higher) arithmetic, though always distinct from arithmetic in the sense of "elementary calculations").

Multiplicative order - Wikipedia
WebIn mathematics, the order of a finite group is the number of its elements. If a group is not finite, one says that its order is infinite. The order of an element of a group (also called period length or period) is the order of the subgroup generated by the element. WebNumber theory in its most basic form is the study of the set of integers Z = {0,±1,±2,...} and its important subset N = {1,2,3,...}, the set of positive integers, sometimes called the natural numbers. They have all kinds of amazing and beautiful properties. The usual rules of arithmetic apply, and can be deduced from a set of axioms. shut down the electricity
