-5 to a set number is -5

To any set that contains it! It belongs to {sqrt(5)}, or {45, sqrt(2), pi, -3/7, sqrt(5)}, or irrational numbers, or real numbers between -3 and 3 etc.

To any set that contains it! It belongs to {-5}, or {45, sqrt(2), -5, pi, -3/7}, or all whole numbers between -43 and 53, or multiples of 5, or integers, or rational numbers, or real numbers, etc.

5 belongs in the sets: -Natural number set, positive whole numbers -Integer number set, whole numbers -Rational number set, numbers that are not never ending -Real number set, basic numbers without i and that can be expressed in say amounts of apples -Complex number set, the set that contains both real and unreal numbers

They are all sets that contain it. It belongs to {-400}, or {-400, sqrt(2), pi, -3/7}, or {-400, bananas, France, cold} or all whole numbers between -500 and -300, or multiples of 5, or negative composite numbers, or integers, or rational numbers, or real numbers, or complex numbers, etc.

To any set that contains it! It belongs to {-3.15}, or {-3.15, sqrt(2), pi, -3/7}, or all numbers between -4 and +5, or negative numbers, or rational numbers, or real numbers, or complex numbers, etc.

To any set that contains it! It belongs to {-5}, or {45, sqrt(2), -5, pi, -3/7}, or all whole numbers between -43 and 53, or multiples of 5, or integers, or rational numbers, or real numbers, etc.

It belongs to any set that contains it: for example, {4.75, -12, pi, sqrt(5), 29}. It belongs to the set of integers which is a proper subset of rational numbers which is a proper subset of real numbers which is a proper subset of complex numbers. So -12 belongs to all the above sets.
