[Justin]

Construct deductions for each of the following using statement.
i
1. R->P
2. Q->R /therefore Q->P
(cant type the symbol)

ii
1 R&S
2.Q->R /therefore P

Derive the indicated conclusion from the premises supplied
i
1. ~S v ~R
2. P-> (S&R) /therefore P

ii.
1. F->R
2.L->S
3.~C
4.(R&S)->C /Therefore ~F v ~L

iii.
1. ~L->(~P->M)
2.~(P v L) /Therefore M

On the first ii, there is no previous reference to P so something is wrong. And on the second i, if ~SV~R is given, at least one of those must be true meaning at least one of S&R must be false making that whole conjunction false, making P false since T->F would be false so ~P would be true, not P, so something is wrong there too.

Unless I misunderstood what you are doing, in which case never mind.
