Nm I got it. Nm I got it.
Nm I got it.

[eq]
2 = 1 + 1
2 = $\frac{1}{2}+\frac{1}{2}$+$\frac{1}{2}+\frac{1}{2}$
[/eq]
but 1 = -1 so
[eq]
2 = $\frac{-1}{2}+\frac{1}{2}$+$\frac{1}{2}+\frac{1}{2}$
2 = 1
[/eq]

ok
1=-1
subtract 3 on both sides, -2=-4,
divide by -2, QED

i donno, i was thinking you could do it with some simple shit and i started out with adding 1/2 to both sides and after staring at it for a while i realized subtracting 3 was quicker

Quoted By:

1 = -1

Adding 1 to both sides, we obtein 1+1=0. Therefore we are working in a field of characteristic 1 or 2. In the latter case OP's conclusion is clearly wrong.

1 = -1 is false, therefore any proposition follows from it, in particular, the statement 2 = 1

Quoted By:

But any such implication is false in GF(2), where 1 is its own additive inverse, so 1 = -1, but 2, if it exists at all, equals 0. ( and 1 and 0 are distinct. )
