- When subtracting the largest number from the smallest number,
- a pattern emerges:
- 1. If the numbers have the same digits,
- the difference will always be zero.
- 2. If the numbers have different digits,
- the difference will be the highest digit value minus the lowest digit value.
- For example,
- subtracting 9876 from 19842 gives 10,566 (8 – 1 = 7, 9 – 1 = 8, 8 – 7 = 1, 6 – 6 = 0).
