Hello!
I have a question regarding an embedded conditional. Does the interpretation change on the base of where the comma is located at like the following exmples? Thanks for your help in advance, I appreciate it!

If S, then /B unless F
= S → /B unless F
= S → (B→F)
= S and B → F

If S, then /B, unless F
= /F → (S→/B)
= /F and S → /B

Answer ----------
[S and B -> F] and [/F and S -> /B] are the same!!!!!!!!!!!!
