Hi, do you mean, why does the inequaltiy sign change, when you divide by a negative number? Can you make your question clear enough,for us to help you out?

You can provide an example. Let's see to it that your grade does not get lower,okay?

Assuming that you are asking about division by negative numbers, lets take a simple example.

We know that 3 < 5.

Which of the following is true:

A) -3 < -5? or

B) -3 > -5?

B is true, right.

Given that 3 < 5, if I want to multiply both sides by -1; what should happen to the sign? Shouldn't the sign change based on the above example.
