- Digit Reduction
- ---------------
-
- This is the starting point for some investigative work.
-
- Choosing <Digit Reduction> opens a similar window to <Kaprekar>. Type a
- number into the writable icon at the top and either press <Return> or click
- on <OK>.
-
- Digit Reduction uses that number to create a multiplication table and to add
- up the digits of the product until there is just one digit left.
