I have spent some time on the google path finding all sorts of conflicting information about the precedence of unary signs, but it still comes down to the simple fact that -2 squared is 4
not -4. Makes no difference what the precedence of the operations are -2 * -2 is 4 and I woudl therefore conclude that -2^3 is -8 as it is -2 * -2 = 4 * -2 = -8.
