It's sad the number of stores I've seen where they just shut down when they can't use the checkout machines; the clerks aren't allowed to do math even if they could.

Whereas the smaller, owner-run stores have more leeway; the local tiny grocery "sold" all freezer/refrigerator food for cheap/free during a power failure. The big Walmart closed and threw everything away the next day.

The odd thing is that the US has been teaching math using the “in your head” heuristic (New Math) for almost 20 years and yet young adults cannot make change without the machine to save their lives.

God help me if I hand someone $25 for a $14.75 total. I’m getting small bills back.

I wonder what they teach in Germany.
