There is only one set and it does have an additive identity.
Yes, it does.
The set of integers (ℤ) is the set of the positive whole numbers and their additive opposites (the negative whole numbers).
The set of integers.
Wrong! Not only is zero a real number, but it is the additive identity for the set of integers, rational numbers as well as real numbers.
There is only one set and it does have an additive identity.
Zero is the additive identity in the set of real numbers; when you add zero to any number, the number does not change its identity.
Yes, it does.
The set of integers (ℤ) is the set of the positive whole numbers and their additive opposites (the negative whole numbers).
The set of integers.
Yes. The additive identity is 0.
To give the set closure with respect to subtraction, or to give it an additive identity.
0 is the additive identity for the set of numbers.
i dont even flucking know
The set of whole numbers includes all their additive opposites. So the set is the same as the one you started with.
The additive identity for a set is a number (denoted by 0) such that a + 0 = 0 + a = a for all elements a which belong to the set.
