Quizplus · Accepted Answer

When we multiply both sides of an inequality by a negative number, we are essentially multiplying both sides by -1. This changes the direction of the inequality. For example, if we have 5 < 7, and we multiply both sides by -1, we get -5 > -7. Therefore, the inequality symbol is reversed.
