the difference between a subset and a proper subset

Equal sets are the sets that are exactly the same, element for element. A proper subset has some, but not all, of the same elements. An improper subset is an equal set.

I don't think such a term is used in set theory. A proper subset, on the other hand, is a subset of the set, that is not equal to the set itself. The difference is comparable to the difference between "greater than" and "greater-or-equal", for real numbers.

S is a proper subset of T ifall elements of S are in T andthere is at least one element of T which is not in S.S is an improper subset if the second condition does not apply.

There is no difference between improper subset and equal sets. If A is an improper subset of B then A = B. For this reason, the term "improper subset" is rarely used.

Because every set is a subset of itself. A proper subset cannot, however, be a proper subset of itself.

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: ⊂, &sub;, &#8834; Subset (or equal): ⊆, &sube;, &#8838; Proper subset: ⊊, &#8842;,

Proper subset definitionA proper subset of a set A is a subset of A that is not equal to A. In other words, if B is a proper subset of A, then all elements of B are in Abut A contains at least one element that is not in B.For example, if A={1,3,5} then B={1,5} is a proper subset of A. The set C={1,3,5} is a subset of A, but it is not a proper subset of A since C=A. The set D={1,4} is not even a subset of A, since 4 is not an element of A.
