I'm finding this chapter rather hard and I'm really struggling with some of the exercises. I hope I'm not the only one. smile

The first of my many issues, is exercise 6.20. Am I at least on the right track, any suggestion of how to move on?

I'm not anywhere near Ex 6.20. I'm stuck on some of the earlier stuff. I can quite clearly determine if the conlcusion of a problem is a consequence of the premises or not, and quite easily provide an informal proof - but translating this into Fitch is proving to be more frustrating than I care to mention.

Good luck.

I might be way off track but does it work if you replace 17 with 16 and delete 17 completely?
