There are several pairs of numbers that add up to 9, including (0, 9), (1, 8), (2, 7), (3, 6), (4, 5), and their negative counterparts like (-1, 10) or (-2, 11). Additionally, you can also use three numbers, such as (2, 2, 5) or (1, 1, 7). The combinations can vary depending on how many numbers you want to include.
