Thanks in advance

It does not seem to follow. Consider the assignment where p, q, r, s are true and t, u are false. Then it seems to me that all premises are true but u is false.

Also, could you write an example of inference? There are dozens of way to write proofs, from completely formal to English text. I don't know what style you use. - Nov 25th 2009, 01:08 AMTurboManX
