How can I turn on my numeric keypad that is part of my Apple keyboard?

I must have hit some unknown key, because I now can't make the numeric keypad (part of my Apple keyboard) work with the Calculator application. It has worked in the past. How can I turn it back on?

  • On a mac computer, go to system preferences (under the 'apple symbol'). Select 'accessibility', and look under the section called 'interacting' for 'mouse and trackpad'. Here be certain that 'enable mouse keys' is NOT checked.
