M = p 1 a 1 p 2 a 2 p 3 a 3 p n a n . Is there a formal proof for $(-1) \\times (-1) = 1$? It's a fundamental formula not only in arithmetic but also in the whole of math.

Is there a proof for it or is it just assumed? Aug 30, 2010the formal moral of that example is that the value of 1i 1 i depends on the branch of the complex logarithm that you use to compute the power. You may already know that 1 =e0+2kiπ 1 = e.
