The identity, i, is a member of a set which, in the context of a mathematical operation, has the property that for every element x in the set: x @ i = x = i @ x For real numbers, if you take @ to be addition, the identity is 0. If you take @ to be multiplication, then the identity is 1.
For every real number, x, which is not zero, there exists a real number x' such that x * x' = x' * x = 1, the multiplicative identity.
They have no real relations ofther than being mathmatical properties The additive identity states that any number + 0 is still that number; a+0 = a The additive inverse property states that any number added to its inverse/opposite is zero; a + -a = 0
The set of real numbers contains an additive identity - which is denoted by zero - such that, for all real numbers, x, x + 0 = 0 + x = x.
hahaha no i wish he was he would be awesome
