I didn't obtain 1.38*10 to the -5 for R and do not know how you obtained the remaining steps. I need assistance

what if we were looking for the vector electric field that 6nC and -3nC charges would create together at the origin? I know the answer is (-0.599i-2.69j) but why are the values negative?
