**Damon**, Friday, January 9, 2009 at 8:00pmNo, on two counts

-125 + 3 = -122

-125 - 3 = -128

25 * -5 = -125

-125 -3 = -128

**Damon**, Friday, January 9, 2009 at 8:02pmLook at what you are doing on a number line, negative is left. More negative is more left.

**Damon**, Friday, January 9, 2009 at 8:05pmOh, I bet I know what caused the confusion:

If you multiply or divide two negative numbers you change the sign to positive.

HOWEVER

That does not happen when adding.
