DETECTIVE COMICS - #468 (1977 - FN/VF)
The Calculator has immunized himself to six members of the Justice League's attempts to capture him, but Batman resolves to give it another try. Using all the arsenal from his Utility Belt, Batman is able to distract Calculator long enough to set a trap perfectly designed to prevent Calculator from escaping, proving that his deductive and thinking skills are much better than a Calculator's machine. With his software overloaded trying to figure a way out of the trap, Calculator is finally stopped after a long series of crimes.
