1. Statements joined by “And” (Conjunctions)
Example1
3+4 = 2
And
3+3=6
FALSE
FALSE
TRUE
Example 2
4 – 2 = 2
And
5 + 3 = 8
TRUE
TRUE
TRUE

2. Solving Statements joined by “And”
Find the solution set for each Individual statement.
Find the Intersection of the individual solution sets. This gives the Final Solution Set.
Express the Final Solution Set in Interval Notation.
Remember: You’re trying to find values that will make BOTH statements True!!!

3. Example 1
Solve the “and” statement.

FALSE

8. Solving Statements joined by “Or”
Find the solution set for each Individual statement.
Find the Union of the individual solution sets. This gives the Final Solution Set.
Express the Final Solution Set in Interval Notation. Make sure a value is not written twice.
