Not only is the symbol daunting, but the words are too

OK, so that is indeed correct. We indeed have that
1 + (0 + 1) = (1 + 0) + 1 = 0 But that is not were the error was. The error is in the following 1 + (1 + 0) = (1 + 1) + 0 = 1 + 0 = 1 So can you calculate 1+(1+0)=... (1+1)+0=... again and see where the error is?

1 + (1 + 0) = 1 + 1 = 0 (1 + 1) + 0 = 0 + 0 = 0 But 1 + (1 + 0) from A2 says 1 + (1 + 0) = (1 + 1) + 0 = 0 + 0 I don't see the error

Impossible I had 0!!! It was in post#29!!!
Oh well at least I got the other 7 right! ahahhaah Wait, does that mean I will have 8 x 8 = 64 lines to write for all the other ones...?

Yes, now try to do the other ones. This should be quite easy if you understood this one.

OK, for A4, you need to use that 1=1 and 0=0. You define this to be so.

Yes because 0*0 is not 1...!

Well, you need to find for each x, an element y such that
x+y=0 By definition, this element is x. So, for x=0, you need an element such that 0+y=0. When you look at the axioms, you see that y=0 is the only possibility. So 0=0. Now, what is 1?

Oh is it from 1 + 1 = 0, that 1 = 1? oh okay
