How do I prove If a > 0 then -a < 0?
That makes sense. Is there another way to prove this statement?
Yes, we can also prove this using the properties of inequalities. If we multiply both sides of a > 0 by -1, we get -a < 0. This is because when we multiply an inequality by a negative number, the direction of the inequality sign is reversed. Therefore, if a > 0, then -a < 0.
