-3 x -3=9 A rule in pre-algebra summarizes in a problem when their is an odd amount of odd - (negative numbers) then the answer is negative, if it is even is is positive.
So the problem is asking, the opposite of three times the opposite of three equals 9, so lets take one of those opposites away. The opposite of three times three equals opposite of nine. (If you haven't noticed, negative and opposite are interchangeable.) And another opposite and get the original problem, the opposite of three times the opposite of three equals 9. So the opposite of the negative nine from the first multiply, is positive nine.
Example
-3 x 3= -9 (1 negative)
-3 x -3= 9 (2 negative, the opposite of the opposite.)
Tips- It is easier to think as two - - = +,
DO NOT MISTAKE THIS WITH ++=+, IT DOES NOT EQUAL A NEGATIVE.
THIS ONLY WORKS WITH MULTIPLYING AND DIVIDING.
