🔍 Explanation:

Each problem is a simple subtraction fact where we subtract the bottom number from the top number. For example:
- `10 - 2 = 8` because 10 minus 2 equals 8.
- `18 - 9 = 9` because 18 minus 9 equals 9.
- `0 - 0 = 0` because zero minus zero is zero.

All answers are within the range of 0 to 18, as expected for "subtraction facts to 18."

This kind of practice helps build fluency in basic subtraction skills, which is essential for arithmetic proficiency.
