And now you understand why the striped socks are so popular. I was going to donate you 100 euros, but I will take them back as the payment for this lesson. I tip my imaginary fedora to you, though.

One final time:
If [math]-1\neq a\neq0[/math], then [math](1+a), -a\in\mathbb{K}^+[/math]. Assuming it is a group, it must then contain [math](1+a)+(-a)[/math], but [math](1+a)+(-a)=1+(a-a)=1[/math]. Maybe you just forget about fields and go play with limits and stuff.
