i finally figured it out from an error message.
i put in 'solve(a+b/c),c' and it told me that 'a+b/c' wasn't an equation. so i entered:
'solve(a+b/c=0,c)' and bob's your uncle!! i found that:
'solve(a+b/c=d,c)' also works.
so, only two days to figure out that simple item. and i did that without being able to figure out how to edit an entry, so i had to reenter the whole equation each time. and i still haven't figured out how to drag and drop although the cursor turns to a hand.
y'know, why is all this crap so difficult? i'm getting too old to devote a year of my life to learning a non-intuitive calculator.
i did figure out how to do a temperature conversion and it's just as convoluted as the hp50 way--you have to go back and forth into a menu about 4 times unless you want to figure out how to type in the 'degree' symbol i guess. and so far there's no sight of the hundred+ flags of the hp50 nor an equation library. there are 'activities' to download, but i find very few of them useful without opening both their accompanying word and pdf files anyway, so why even bother with the calculator? just download the pdfs.
the templates section looks interesting and i will gradually sneak up on those as i go along. but they are represented as tiny icons, not text--and no little text balloon pops up to tell you what the templates are for.

that's the hp way. but i can't find a similar structure on the nspire cas.

'a+b/c=d'
'c'
ISOL
c=-b/(a-d) will be returned on the stack
Is that the type of thing you're looking for?
