2.  Working backwards  Do any of the phrases appear in the string?  Check for each phrase independently  If any appears, condition is TRUE  If TRUE, then type "True Blue", else type "Not True Blue"

3.  Functions: FIND, SEARCH  Both return ERROR if not found  ISERROR returns TRUE if error  How do I get a TRUE if found?

4.  IF “UNC” is FOUND OR “Heels” is FOUND  IF FIND(“UNC) is NOT an ERROR OR FIND(“Heels”) is NOT an ERROR  OR( NOT(FIND(“UNC”)), NOT(FIND(“Heels”)) )

5.  TRUE and FALSE are simply two branches  But sometimes its easier to think AND rather than OR  It is NOT TRUE BLUE if all of the searches fail (AND)  It is TRUE BLUE if any of the searches succeed (OR)

6.  Consider the following two statements: If A is false or B is false If A is true and B is true  Let’s look at the truth table: ABNOT A or NOT BA and BNOT (A and B) 00101 01101 10101 11010

7.  5A+5B == 5(A+B)  Well, in Boolean… ~A OR ~B == ~(A AND B) ~A AND ~B == ~(A OR B)

8.  OR( NOT(FIND(“UNC”)), NOT(FIND(“Heels”)) )  NOT( AND( FIND(“UNC”), FIND(“Heels”) )

9.  What if not a blank after UNC?  See True Blue Worksheet

10.  Using PROPER causes the following quirk: I’Ve John’S  Is there a way to fix it? See Apostrophe Worksheet
