Pick 4 different numerals from 0 - 9 and arrange them to make the largest possible number.
| | for example: **8732** | |
Now arrange the same numerals to make the smallest possible number.
| | **2378** | |
Subtract the smaller number from the larger.
| | **8732-2378=6354** | |
Arrange the numerals in the answer to make the largest and smallest possible numbers, and subtract those numbers.
| | **6543-3456=3087** | |
Continue with this process until you end up with 6174.
| | **8730-378=8352** 8532-2358=6174! |
Does it always work? Try 4 new numerals and see if you can end at 6174 every time!
