(-1^2+-1^-2)^-1

(-1^2+-1^-2)^-1 =
First, do work within the parentheses.
-1*-1 = 1 and -1^-2 = 1/(-1²) =
[1+(1/(-1²)]= [1 + 1/1]^-1. (One moves the negative exponent in the numerator by making it 1/(the positive exponent; thus, -1^-2 becomes 1/(-1)².
Now flip the -1 exponent by taking the reciprocal.
[1/(1+1}] = 1/2
