Flip it when you multiple or divide by a negative number from one side to the next.

You need to flip the sign only when you multiply or mulptiply both sides by a negative or a minus number.
For example,
-(x/2) > 4
-x > 8
Now you have to convert "x" into a positive digit.
In order to do so you have to divide both sides by (-1).
x < (-8)

Hope it helped.
