Identidad 3
In MATHEMATICS, the term identity has several important uses. In one of them, identity can refer to an equality that remains true regardless of the values of any variables that appear within it, to distinguish it from an equality which is true under more particular conditions. The symbol ≡ is sometimes used to indicate a mathematical identity (or a congruence relation).
On the other hand, a common example of an identity element is the number 0 among the real numbers under addition. This means that for all real number a:
0 + a = a
a + 0 = 0
and
0 + 0 = 0
