conditional chain linkage with "if but only if"/double arrow

matteejay

Hi guys,
So I know that for example A ---> B <--|--> C leads to the inference A <--|--> C, whereas A <--|--> B ---- > C leads to no useful inference. What about the double arrow? i.e.
1) A <---> B ---> C
2) A ---> B <---> C

my gut tells me in both cases its just A --- > C but I'm not 100%. Can anyone shed some light on this?
Cheers

Yes A-> C in both cases! Because
A<-->B means A->B AND B->A so look at which the arrows go.
