When you see 1e-3 on your calculator, that means 1 x 10^-3, which is scientific notation. If you are asked to find the log of 10^-3, just remember that a logarithm IS an exponent, so as long as you are in base 10, the answer will be whatever the exponent is, in this case, -3.
If you were asked to find the log of 1E-5, the answer would be -5.
