"Unless" statement Brainfart!
N cannot be selected unless L is selected.
Isn't this supposed to diagrammed as L --> N?

No. N--->L
if N is selected, you know L has been as well because N can only be selected if L is.

Could you explain the process of getting to your diagram?doyleoil wrote:just the opposite (meaning, N ---> L)brooklynballers wrote:N cannot be selected unless L is selected.

Re: "Unless" statement Brainfart!
Umm it's been a while, but wouldn't it be:
~L --> ~N
~L --> ~N

Re: "Unless" statement Brainfart!
This isn't a bad place to start, because I think the best, most common sense, way to get to the diagram is to say to yourself "what happens if L isn't there?" If L isn't there, then N isn't there. And the contrapositive of that is "N ----> L"agentcom wrote:Umm it's been a while, but wouldn't if be:

Re: "Unless" statement Brainfart!
So you could select L, but not necessarily select N right?

Re: "Unless" statement Brainfart!
So the best way to think of it would be:blackwater88 wrote:unless: if not
DONE
N can not be selected (if not) L is selected
OR
N can not be selected if L is not selected.
Which gives us:
If L is not selected, then N is not selected.
Contrapositive:
N --> L

Re: "Unless" statement Brainfart!
"if not" works. Some people have just as hard of a time with if not as they do with unless though, and if that is the case, just think "whatever comes immediately after unless goes on the right side, the other thing goes on the left and negated."

I like the 2nd one bolded above more. It is less confusing and faster since it is pretty brainless and mechanical with less translation steps.Audio Technica Guy wrote:"if not" works.

Re: "Unless" statement Brainfart!
To me "if not" works much faster, to be honest I first learned the bolded part, when I thought about "if not" it made me doubt since I didn't grasp the concept of "unless" that well. However, if you just take it as it is and substitute "unless" for "if not" every time it appears, there really is no transitional thinking. Just like you should memorize that all As are Bs = A ==> BJeffort wrote:I like the 2nd one bolded above more.

Re: "Unless" statement Brainfart!
If you're using the logical reasoning bible, check out page 126 and maybe review all of chapter six. Basically what is explained here is correct; if you see the word "unless" (and some other words like until or except) whatever is modified by this becomes the necessary condition.
