Actually, Google is right. sqrt(-1^2) = sqrt(-(1^2)) = sqrt(-1*1) = sqrt(-1) = i sqrt(-i^2) = sqrt(-(i^2)) = sqrt(-1*-1) = sqrt(1) = 1
-1^2 != -(1^2) :rolleyes:

This is what wikipedia says about Order of Operations: There exist differing conventions concerning the unary operator - (usually read "minus"). In written or printed mathematics, the expression -3² is interpreted to mean -(3²) = -9, but in some applications and programming languages, notably the application Microsoft Office Excel and the programming language bc, unary operators have a higher priority than binary operators, that is, the unary minus (negation) has higher precedence than exponentiation, so in those languages -3² will be interpreted as (-3)² = 9. [1] In any case where there is a possibility that the notation might be misinterpreted, it is advisable to use brackets to clarify which interpretation is intended.

You're lucky they even allowed it to be presented. Maybe their legal department didn't see it yet. Though they could probably get away with it if they included a disclaimer, or changed it to a capital I.

I will concede the point that parenthesis are needed.

i? What is that, some kind of imaginary number?
