Search function?

Is there a specific search box for the discussion board (not control + F)? Am I just blind?

It had poor functionality so they got rid of it while they retool. What are you looking for in particular?

In many other forums people get annoyed if you ask a question that has already been asked.. so I just wanted to check before I posted!

PT 66 Section 4 Question 20.

Conditionals aren't usually an issue for me but I had trouble interpreting "Without such marketing we will be unable to increase our enrolment"

when I draw out the conditional, not following any particular rule but in a way that makes sense from reading, I get "/M --> /IE" or "IE --> M" .. which is right I believe?

However, when I try and use lawgic I mess it up..
negate sufficient (using without as an indicator) /M --> IE or /IE --> M

does the word "unable" mean that IE is negated as well? .. but then if that is the case if I picked IE as my negate sufficient word I would get IE --> /M

Not sure why this conditional in particular is giving me so much trouble.. think I'm having a brain fart.

Unable is a negation. So either use that as a group four negate necessary and use the without as a negation, or use without as a group three negate sufficient and use unable as a negation. In doing so you either get what you originally thought it was, or the contrapositive.

In your last example you would not negate M in the necessary because you're already using up the without as a group three indicator. A word cannot serve as both an indicator and as a negation.
