There is a hierarchy of sets:
No, because there are an infiite number of sets that contain -5. For example {-5, 8}, which does not even have a name.
Natural numbers.
With math for most people, the set of complex numbers can be considered to enclose all other sets of numbers.There are, however, sets of numbers that have been created which are outside the scope of 'complex numbers'.
there are 5 diffeerent sets Natural Numbers whole numbers integers rational numbers irrational numbers.
the answer is -1
The union is all the numbers in all the sets.
Ratioal numbers
-5
There are 376740 such sets and you must think me crazy if you think I will list them all!
-3

they are almost all equivalent - whole numbers also have the number 0, which natural numbers (counting numbers) do not.
There are infinitely many sets: Some examples: {346}, or {346, sqrt(2), pi, -3/7}, or all whole numbers between 43 and 530, or multiples of 2, or composite numbers, or counting numbers, or integers, or rational numbers, or real numbers, or complex numbers, etc.
-28 belongs to: Integers, which is a subset of rationals, which is a subset of reals, which is a subset of complex numbers.
Integers, rationals. Also all subsets of these sets eg all even numbers, all integers divided by 3.
