I have about 10 questions, I hope someone can take the time to help me with. The directions are: "Use the 18 rules of inference, supply a proof for each of the following arguments." So, here goes:(adsbygoogle = window.adsbygoogle || []).push({});

1.) 1. (R v X) > (A > B)

2. ~ Q > ~ C

3. ~ C > Z

4. R .Y

5. Q v A /Z v B

2.) 1. E . (P . B)

2. (E . B) >~ (P.~M) /E.M

3.) 1. ~(S v C)

2. ~(S . R) > (C v D) /D

4.) 1. D > P /(I . D) > P

5.) 1. P v (Y . H)

2. (P v Y) >~ (H v C)

3. (P .~ C) > (K . X) /X v T

6.) 1. A = J

2. A v J

3. A > (J > W) /W

7.) 1. ~Q> (C . B)

2. ~T> (B . H)

3. ~(Q . T) /B

8.) 1. (U . P) >Q

2. ~ O > U

3. ~ P > O

4. ~ O . T /Q

9.) 1. (J>K) . (~O>~P)

2. (L > J) . (~M>~O)

3. ~K> (L v~ M)

4. ~K . G /~P

10.) 1. (F . M) > (S v T)

2. (~S v A) > F

3. (~S v B) > M

4. ~S . G /T

Okay, that's all the questions. Now here is the legend key:

/ separates what the conclusion is supposed to be.

. conjunction

v disjunction

> implication

= biconditional

~ negation

This is for an introductory to logic class. I hope someone can help. Thank you.
