**Exercises on Disjunctions**

*State the truth value of the following statements.*

**1. If p is true and q is false, state the truth for:~ p V q2. If p is false and q is true, state the truth for:p V ~ q3. If p is true and q is false, state the truth for:~ p V ~ q4. If p is false and q is true, state the truth for:p V q5. If p is false and q is true, state the truth for:~ p V q6. If p is false and q is false, state the truth for:p V q7. If p is true and q is false, state the truth for:~(~ p V ~ q )8. If p is true and q is true, state the truth for:p V q9. If p is true and q is true, state the truth for:~ p V q10. If p is false and q is true, state the truth for:~ p V ~ q11. If p is true and q is false, state the truth for:~( p V q )12. If p is false and q is true, state the truth for:~(~ p V ~ q )13. If p is true and q is false, state the truth for:p V ~ q14. If p is false and q is false, state the truth for:~ p V q15. If p is false and q is false, state the truth for:~(~ p V ~ q )16. If p is false and q is false, state the truth for:p V ~ q17. If p is true and q is true, state the truth for:~(~ p V ~ q )18. If p is false and q is true, state the truth for:~(~ p V q )19.

Hi Devante!

These truth value evaluations are much easier if the statements are first translated into the G. Spencer Brown notation. His notation has only one symbol (like the upper righthand corner of a square) besides the statement variables p,q,r, etc. Look up his system on the internet. You'll be amazed at his ingenious system.

Writing "pretty" math (two dimensional) is easier to read and grasp than LaTex (one dimensional).

LaTex is like painting on many strips of paper and then stacking them to see what picture they make.
