the number of adults i've met who cannot add two fractions together is depressing.
at some point each of them had decided "i'm just bad with numbers, hahaha" and they gave themselves permission to stop trying math. worse, society gives you a pass at not knowing math. we need to apply the same constant social pressure to mathematics skills that we do for learning to read.
An inability to understand compound interest is classic.
I think we're more talking about algebra or, really, anything "higher" in maths than arithmetic. Does a solid knowledge of, e,g, Set Theory, give any benefit later in life?
And also, if we think that basic financial management is a good thing for kids to learn, why don't we teach that?
Ha Ha Ha! Cute you think society cares about reading abilities!
I mean, OK, you are expected to be able to do basic level reading. But, say, reading something independently to learn something? Even when I was in university 20 years ago it was a struggle to get people to read.
