Keyboard 10 key not working

[smhardesty]

All modern keyboards have a 10 key on them, don't they? This quote was taken directly from Wikipedia.

A numeric keypad, number pad, numpad, or ten key, is the palm-sized, 17-key section of a standard computer keyboard, usually on the far right. It provides calculator-style efficiency for entering numbers. The idea of a 10-key number pad cluster was originally introduced by Tadao Kashio, the developer of Casio electronic calculators.

And this is the image that Wikipedia has on that page. Modern keyboards have 17 keys instead of the actual 10 key that they originally had.
