Re: Linear--structure or property?

FW: categories: Re: Linear--structure or property?Dear Florian,

1*2 = f(f(1)+f(2)) = f(1+3) = f(4) = f(2x2) = f(2)xf(2) = 3x3 = 9.

You are right, and thank you the correction (I think I thought of 3*3 = f(f(3)+f(3)) = f(2+2) =..., but does not matter of course). Dear Bill, Having two structures in {0,1} (with 1+1 = 0 and with 1+1 = 1) makes what you say about the Tarski school funny (sorry!) Best regards to all- George
