    i would think that the 'opposite of the opposite of' is the number itself

    So for -5 it would be -5.

    it is false because: starting from the number x (with x<0); take the opposite by multiplying it by (-1), getting (-x), a positive number; then take again the opposite of this new number by multiplying it by (-1), getting (x), a negative number. In other words, if you take the opposite of a number "x" once, three times, five times, etc. , then the result is the same number but with the opposite sign (e.g. 5 becomes -5). While if you take the opposite of a number "x" twice, four times, six times, etc., then the result is exactly the same starting number "x" (5 rests 5).
