Iroquois Algebra Blog: Set Operations

In class on Monday, you will receive a packet entitled "Set Notation and Set Operations". Here is a site with a video and notes that review the operation of complementation (finding the complement of a set):

Note that this site uses the "prime" (apostrophe) notation to indicate the complement of a set, e.g., A' means "the complement of set A". There are other notations for the complement of a set, as shown in the packet. You should be familiar with all of these notations. Also, note the definition and notation for null set and empty set, which are synonyms referring to the set that contains no elements.

This video reviews the set operations of intersection and union:

Note the use of interval notation. :-)
