Not sure where the typo is, but assuming you meant 7 and not 12, your reasoning is correct. You can do it the way you did, subtracting the larger from the smaller, or you can do
|7 - (-15)) = |7+15| = 22
Personally, I prefer subtracting the smaller, but...
Find the distance between -15 and 12 on a number line.
this is what i came up with but im not sure if its right...
|-15 - 7| = |-22| = 22 units
