pH = -log[H+]
-log[.001]
-(-3)
pH = 3

You got it right!
pH is the negative of the log of the H+ ion concentration, in mols/liter.
HCl is a strong acid, so it totally dissociates into H+ and Cl- ions at dilute concentrations. Therefore the concentration of H+ ions is 0.001 mols/L. The log of this is -3, and the pH is 3.

take the negative log of 0.001
