Austen said it better than I did.
And what also stood out in the OP’s post is the comment that “getting started” on a problem is a hurdle. Those are the sales people at Home Depot who can’t help you figure out how much carpeting you need (I have had this problem and NOT picking on Home Depot here). These are the dreaded “Word Problems” which if you uncouple it from the arithmetic (it’s just multiplying after all- and the sales people all have computers and calculators)… If Blossom’s living room is 10 X 12 with a 5X6 adjacent alcove how much carpet does she need?
And more critically- these are the people heading off to pay H&R Block with the simplest of tax returns because they are flummoxed trying to add their modest interest and dividend income to their wages without including the capital gains (and they don’t understand the difference between dividends and capital gains anyway_.)
Feeling comfortable with core, HS level math skills is going to serve the D for the rest of her life…
