Three digits can't possibly add up to 900. The largest possible sum of 3 digits is (9 + 9 + 9) = 27.
3, 7 and 9. 4 odd digits that add up to 19 would be 9, 9, 0.5, 0.5

There are a variety of three digits that add up to 25. Examples include 9, 8 and 8.
To make the list of two-digit numbers with digits that add up to 10, first write the pairs of single-digit integers that add up to 10. They are (1,9), (2,8), (3,7), (4,6), (5,5). Then recognize that each of these pairs of numbers, except 5, can be combined in two different ways to make two-digit numbers that satisfy the problem. 19 and 91 28 and 82 37 and 73 46 and 64 55 So there are nine two-digit numbers with digits that add up to 10.
Presumably because the digits on their hands add up to 10
