Additive Identity: For any rational number a/b where b is not equal to zero, 0+a/b = a/b+0 = a/b. Therefore, zero is the identity element for addition in rational number. Example: 0+7/9 + 7/9+0 = 7/9
Additive Inverse: For any nonzero rational number a/b, there exists a unique rational number a/b such that a/b + (a/b) = 0. a/b and a/b are additive inverses. Each one is called the additive inverse of the other. Directions: Answer the following questions. Also write at least 10 examples of your own.
