Question

What is the difference between a subset and a proper subset?

{5,8}
{2,5,8}

Is {5,8} a subset of {2,5,8}? please explain.

Answer 1

A subset is when all of the elements in the subset are in the actual set. A proper subset is a subset which the actual set has at least on more element than the proper subset.

Explanation:

For example, Set A, {1,2,3} is a subset of B {1,2,3}. But Set C, {1,2} is a proper subset of B. Set {5,8} is a subset of {2,5,8}.
