Since whole numbers are the same as integers, there are no different rules! The only way in which the rules for natural numbers is different is that the set does not contain the additional opposites of numbers (in other words, the set is not closed under subtraction).
Prime Numbers under 6 are 2,3,5
Avogadro's Law states that equal volumes of gases at the same temperature and pressure contain equal numbers of molecules. This relationship allows for the comparison of different gases under the same conditions.
There are infinitely many subsets of real numbers. For example, {2}, {2, 3}, {2.3, pi, sqrt(37)}. It is, therefore, not possible to list them.The main subsets of real numbers are the rational numbers and irrational numbers.Irrational numbers can be split into transcendental numbers and polynomial roots.Rational numbers contain the set of integers.Integers contain the set of natural numbers.Natural numbers contain the set of counting numbers.
There are 34 prime numbers under 140.
The numbers are not closed under addition because whole numbers, even integers, and natural numbers are closed.
