I am confused a few answers in this truth table:
http://www.philosophyforum.com/forum/philosophy-forums/branches-philosophy/logic/4698-argument-tautologically-valid.html
We have the (A+B) then C
A/B
F/T then F
T/F then F
F/F then F
Supposedly the first of these is False, and the next two are true and I can't figure out why. I would assume the person is mistaken.
My reasoning is that the fact that A+B are bracketed would make (A+B) False in each example, which would leave us with
F then F
F then F
F then F
Which in my mind, in the construction of a truth table would make each True, and not simply the latter two. Some help??? I would be grateful.
Stumble It!

@Horace phil,
I am concerned about line 6,7,8, 14,15, 16 but only the values found under the first therefore sign. To my mind each should be true...
