identity element
Meanings (ES + gloss)
elemento neutro
An element of an algebraic structure which when applied, in either order, to any other element via a binary operation yields the other element.
Proof. If e and e' are both identity elements, then we have ee'=e since e' is an identity element, and ee'=e' since e is an identity element. Thus e=ee'=e'.
Therefore the number 0 is not considered an identity element for subtraction, even though x-0#61;x for all x, since 0-x#92;nex.
