You can put this solution on YOUR website!
How did you start it? I don't see any work. Post what you've tried and I'll gladly help where I can.

\n" ); document.write( "Yes... this is the start

\n" ); document.write( "1. (B ⊃ ∼M) ⊃ (T ⊃ ∼S) Premise
\n" ); document.write( "2. B ⊃ K Premise
\n" ); document.write( "3. K ⊃ ∼M Premise
\n" ); document.write( "4. ∼S ⊃ N Premise

\n" ); document.write( "5.:: B Conditional Proof (CP) assumption #1
\n" ); document.write( "6.:: K 5,2 Modus Ponens (MP)
\n" ); document.write( "7.:: ~M 6,3 MP

\n" ); document.write( "9.::
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "Continue from step 9. Step 9 is an important conclusion from line 8 and line 1. On step 10 you will need to make a 2nd CP assumption of T and show that it leads to N true (which will prove T ⊃ N). \r
