Hey,
I'm wanting to know how to store values on my scientific calc. It is a Casio, but i'm assuming they are all pretty similar.
Whenever I do a chem question, my answer is always slightly off because I use a rounded mol value instead of the calc one which for whatever reason I've had to erase. Obviously in exams i can't do this, so does anyone know how I could store values in my calc?
Thanks.

There should be a RCL button
Above that is STO function, which I think is used for storing numbers
I just bought a Casio, and I'm still learning how to use it :P
-
Yeah, I have exactly that.
found this, works great, thanks!

No problem, just out of interest, what model do you have???

i have the fx-82AU.

ok cool
i got an fx-993 (from Japan) :P
it can do calculus :D

I have an fx-570, just doesn't have the solar panel thing

Ah ok, how much was it around?
Mine was about $60

Lol I had no idea my scientific calculator could store values until after a year of using the TI-84 for Methods.

how tight are vcaa with rounding errors in science?
if your answer is a bit off but the number of sig figs is right, would you still get full marks, or are you expected to never round until the very end?
-
It's not that hard to develop a "never round until the very end" habit. Obviously it's safer so there's really no point with pursuing the former option.

+1, definitely go at least three or four decimal places/sig figs further than your answer when working, then you'll be fine

yeah I'm always going to do that, but it's just a pain especially when you've had to do a mole to mass calculation and then you need to reuse the initial mole value again to do another calculation, but I know how to store values now which will make it a lot easier.
