a subset is a group that is contained within the other group. So the set of letters {a, b} is a subset of {a, b, c} It is also worth noting that {a, b} is also a subset of itself {a, b}. In set arithmatic a subset I believe is defined like this: set1 is a subset of set2 if set1 + set2 = set2. {a, b} + {a, b, c} = {a, b, c}

the difference between a subset and a proper subset
Since ASCII ⊊ unicode, I don't know if there are ASCII codes for subset and proper subset. There are Unicode characters for subset and proper subset though: Subset: ⊂, ⊂, ⊂ Subset (or equal): ⊆, ⊆, ⊆ Proper subset: ⊊, ⊊,
give example of subset
A subset of a set S can be S itself. A proper subset cannot.
A subset is a division of a set in which all members of the subset are members of the set. Examples: Men is a subset of the set people. Prime numbers is a subset of numbers.
