The sum of absolute values represents the sum of distances from a point to point A and point B on the number axis. .

So when you take a certain number between a and b, it is the minimum value.

Then bring in x=a or B, and you'll know it.

|a-b|=2

So a-b=-2 or 2.

So the result is 2023-2=202 1 or 2023+2=2025.
