Na, Sky, two negatives will equal a positive in addition and subtraction. The way I used to imagine this was to take the second minus sign and then plunge it in the first one vertically, of course to make a plus sign.
Unless I'm mistaken in what you meant was a negative times a negative will equal a positive, which is correct.
So Chaos and Dee were right.
glitter . (last post): Absolute values have nothing to do with the "two negatives a positive." Absolute values are what they are: How many places is the number away from zero (not saying "backwards from zero"). Left or right. |-14| is 14 from zero (doesn't matter on direction), so it then turns, appearing and in nature, to a "positive" 14, basically saying "the absolute of -14 is 14 because it is 14 places from zero."
# - (-#) will become # + # (what I was saying about taking second - sign and plunging it in first - sign).
-# * -# = #
-#/-# = #
# * -# = -#
#/-# = -#
... Sorry. I loved math; and, seeing more than one person make mistakes was GRAH. Dx
