Now get real and to the fact - as I had expected by a well read man: The surd symbol, v, is reserved for the positive square root. The surd symbol, applied to a non-negative real number x, thus s returns the non-negative real number y that satisfies y 2 = x. Consequently the principal square root, or in short, just "the square root" always is a positive number and expressed by the surd symbol over the number. All way through my high school and college time the square root was expressed by the surd symbol and a number to go with it and thus denominated a positive number only. Yes, square -2 and you indeed get the second solution to the equation 4 = x high 2 (or x to the 2nd). Taro
