It's different when it's written down as a math expression or word problem. 100-110 becomes 110-100. 17-9 becomes a finger counting exercise. Small errors get propagated in ways that make a distracting mess to sort out. None of this is conducive to learning algebra.

If a kid can do $100-$100 but can't do 20-8, the problem is he doesn't understand how to map the things in real life he knows, to the symbols you're showing him.
