This lesson will explain what a subset of a set is. We will start our lesson with a definition. Definition: Set B is a subset of a set A if and only if every object of B is also an object of A. We write B ⊆ A By definition, the empty set( { } or…

A set-builder notation describes or defines the elements of a set instead of listing the elements. For example, the set { 1, 2, 3, 4, 5, 6, 7, 8, 9 } list the elements.  The same set could be described as { x/x is a counting number less than 10 } in set-builder notation. We…

The different ways to write or define a set is called set notation. However, what is a set? Let us start with a definition of a set. Basically, anything with a collection of objects is a set. Here is an example of set made with odd and even whole numbers less than 10. You may…
