The term "whole numbers" has various interpretations.
Some sources define them as any integer, positive or negative.
Others, especially in mathematics, consider whole numbers as non-negative integers.
Here, we adopt the mathematical definition: whole numbers are zero or positive integers.
To find all pairs of whole numbers summing to 110, we enumerate:
0 + 110 = 110
1 + 109 = 110
2 + 108 = 110
...
54 + 56 = 110
55 + 55 = 110
Since 56 + 54 repeats a previous pair (54,56), we stop at 55 + 55. In total, there are 56 such pairs.
