And I'm amazed how often I see people trying to calculate
change = sum handed over - cost
and then trying to figure out what bills/coins should be returned
instead of doing the simple thing of just adding to the cost.
When I was a kid, making change like that was something we were all
taught in school. I have a feeling that's been dropped from most
curricula.

Not sure about the most recent decade, but back when I was in elementary
school(1995-2001-ish),
we definitely still learned math through how to make change.
Ah, but making change and counting change are not the same thing!
Making change: $3.61 from $10 . . . $6.39
Counting change: $3.61 from $10 --
- (give four pennies back) $3.65
- (give a dime back) $3.75
- (give a quarter back) $4.00
- (give a dollar back) $5.00
- (give a five back) and $10.00!
