I think it's fair to say that, growing up, math wasn't the favorite subject for many of us. In my case, that was partially because math class always seemed to have the most homework and because that work struck me as boring and repetitive.
So, like many who aren't in school anymore, I've noticed a significant atrophy in my math skills that likely would have embarrassed the high school version of myself. And that atrophy was the subject of some concern in Japan as the way 20-somethings there tended to answer one simple question differed significantly from how they did 30-40 years ago.
