Explain why it is necessary to reverse the inequality symbol when multiplying both sides of an inequality by a negative number. Please make sure you provide an example to support your explanation

Question and answer

The inequality sign changes because you are switching the signs of the values in the inequality. So you must flip the inequality sign as well. [ Once all values become negative, that means that negatives are flipped from one side to the other (or abolished, if both sides were negative). If the sign is not flipped, it makes the solution a whole different range of numbers, because it changes the inequality. ]
