WebAs we just saw, putting minuses in front of a and b changes the direction of the inequality. This is called the "Additive Inverse": If a < b then −a > −b. If a > b then −a < −b. This is really the same as multiplying by (-1), and that is why it changes direction. Example: Alex has more money than Billy, and so Alex is ahead.
