Unfortunately, the research only describes the problem adults have with basic math, and the article doesn’t offer any insight into why this is or what solutions.

I test fast food workers a lot when I pay for a meal. For example, on a $4.72 bill I’ll pay $5.22 so I can get two quarters back. It really baffles some of them, to the point where I say, type it in to the register and you’ll see why.
