If this is solar powered, why does it need a battery?

It lasts for years. The solar is working but at night there is no solar so it uses the battery. I was not able to open one of these to replace the battery but it lasted maybe 10 years. This is a good product.

Does this have a "kickstand" to elevate the display?

Yes. It is about a 1/2" when in place.

How do you figure from cost to markdown

It is not clear what type of calculation you are attempting. Some financial calculations are described in the manual. If you do not have the manual handy, then you may want to refer to the online manual for JF-120BM (which is very similar in operation) at the following link: http://www.servicecasio.com/web/download/manual/DF-120BM_DM-1200BM_JF-120BM_FA_DI8S.pdf See the right column of page 2 of this manual.

Do you get the jf-100ms calculator pictured here, or the jf-100bm calculator as stated in the title?

I got the JF-100ms. It works really well.
