What is a subset of records?
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}
An example of why any subset can not be a proper subset?
Assume that set A is a subset of set B. If sets A and B are equal (they contain the same elements), then A is NOT a proper subset of B, otherwise, it is.
What is an proper subset?
Set "A" is said to be a subset of set "B" if it fulfills the following two conditions:A is a subset of B, andA is not equal to B
What is a different from subset and proper subset?
If set A and set B are two sets then A is a subset of B whose all members are also in set B.
What is a subset in maths?
A set "A" is said to be a subset of of set "B", if every element in set "A" is also an element of set "B". If "A" is a subset of "B" and the sets are not equal, "A" is said to be a proper subset of "B". For example: the set of natural numbers is a subset of itself. The set of square numbers is a subset (and also a proper subset) of the set of natural numbers.
