Algebra Topics

Addition
The operation of finding the sum of two or more quantities.
Additive Identity
The additive identity is the number zero, because zero will not change a number when added to it: a + 0 = a for all a.
Additive Inverse
The addition of number and it′s additive inverse is zero. The additive inverse of a number a is -a, also known as the opposite of a, such that a + (-a) = 0. For example, 1 + (-1) = 0.
