For example, if you take the set A = {1, 2}, then the following sets are all subsets of it: {}, {1}, {2}, {1, 2}. That is, all the sets that fulfill the condition that all of its elements are also elements of the set "A".
There are no subsets of irrational numbers. There are subsets of rational numbers, however.
Elements can belong to subsets. Subsets can be elements of sets that are called "power sets".
Once example is the whole numbers and subsets are the numbers 1,2 and 3 written {1,2,3}. Another example is all the colors. Subsets would be any number of individual colors. The universal set may be finite or infinite.
5 subsets of 4 and of 1, 10 subsets of 3 and of 2 adds up to 30.
The subsets of the set {1, 2, 3, 4, 5, 6} include all possible combinations of its elements, including the empty set. There are a total of (2^6 = 64) subsets, which range from the empty set to the full set itself. Some examples of subsets are {1}, {2, 3}, {4, 5, 6}, and {1, 2, 3, 4, 5, 6}. Each subset can vary in size from 0 to 6 elements.
meaning of proper subsets
An element doesn't have subsets. Sets can have subsets.
There are no subsets of irrational numbers. There are subsets of rational numbers, however.
Elements belong to subsets: subsets contain elements (from the parent set).
All rational numbers are real so the phrase "real rational" has no meaning. There are an infinite number of subsets: The emply or null set, {1,1.5, 7/3}, {2}, (0.1,0.2,0.3,0.66..., 5.142857142857...} are some examples.
