The additive opposite of the additive opposite is the number itself.
The multiplicative opposite of the multiplicative opposite is the number itself, unless the number was 0, in which case the first opposite is not defined.
Zero

An integer is just a whole number, excluding zero. Any positive integer will always have an opposite just by placing a negative sign in front of the positive integer. You can also say that any negative whole number is an integer.
yes. the opposite of a positive integer is the same except negative and vice versa ( ex: the opposite integer of -6 is 6. if you multiply them, it equals zero)
the quotient of an integer and its opposite is never negative.
The opposite of an integer is the integer that, when added to it, results in a sum of zero. In this case, the opposite of -6 is 6, since -6 + 6 = 0. The opposite integer is also known as the additive inverse.
Any polygon with 2n sides (n integer) where opposite sides are parallel, will have its opposite angles congruent.
A non-integer.
-1 (interagers are any number and its opposite/negative.)
The answer depends on the context for opposite. Common opposites are the additive or multiplicative inverses but any invertible function can be used to define an opposite.
yes
a negative integer or a fraction (as in 1/integer) or a negative fraction (as in -1/integer).
