Homework Help: math

Posted by jess on Sunday, September 4, 2011 at 12:27am.

We are learning inequalities and I just did some homework but the teacher returned it saying I did some of them wrong.
1. -2x - 10 < 2
2. -2x + 15 < 17
I didn't flip the inequality sign when I divided by (-2).
But why do we always have to flip the sign when we multiply or divide by a negative number?
