Choose operation and number of operands (for adding and multiplication).
You can also choose if you want to allow duplicate numbers or not.

Further filtering is achieved by long touching numbers from 1 to 9.
First long touch makes it red and removes all results containing that number.
Second long touch colors button to green and lists only results which contain that number.
Third long touch reverses that number to normal.
