Remember the table for multiplication/division of positive and negative numbers.
-
X/ + = +
-
X/ - = -
-
X/ + = -
-
X/ - = +
NB If a number does NOT show a sign , read it as positive (+).
NNB 'X/' means 'multiply or divide'.
eg.
2 X 3 = 6 ( all positives)
2 x -3 = -6
-2 x 3 = -6
-2 X -3 = (+) 6

Because if a negative is multiplied by another negative it will always be positive. But, if a positive is multiplied or divided by a negative it will always be negative. If the two signs are the same and or being multiplied or divided they will be positive. If the two signs are different and or being multiplied or divided will be negative. True, but the question is not about multiplication, but addition. i like to think of it like this on a number line there are positives and negatives -3 -2 -1 0 1 2 3 if you added 2 to zero you move up to the number positive 2 then move down two number, which represents subtracting two or negative two. you should end up on zero
