How can I add a combination of 3 digit numbers from 1 to 9and give me the same sum?

To create a combination of three-digit numbers from the digits 1 to 9 that yields the same sum, you can select different sets of three digits that add up to the same total. For example, the combinations (1, 2, 3) and (1, 4, 2) both sum to 6. You can then form three-digit numbers using these combinations, such as 123 and 132, which will still sum the same. The key is to ensure that the chosen digits in each combination always add up to the same total.
