[kde-edu]: Help with UI design

[Sebastian Stein]

Hi folks,

I want to add a new feature to KBruch. The user should separate a given
number into prime factors. For example: 204 = 2 * 2 * 3 * 17

I'm not sure how to design the interface to enter the numbers 2, 2, 3 and
17. I want the possibility to enter each prime factor on its own. And I
don't want the user to enter the *. So any ideas how to design an easy to
use interface for this task?

Sebastian
