Additive Inverse

The additive inverse of a number is the number that, when added to the original number, results in zero. It involves simply changing the sign of the number, which is why the opposite of a negative number is a positive number and vice versa.

Sign Change

Changing the sign of a number is a basic arithmetic operation that transforms negative numbers into positive ones and positive numbers into negative ones. This operation is essential for understanding and working with opposites on the number line.
