For anyone who's interested, I'm finishing up work on a 'Scientific Calculator Comparison' between the CASIO fx-115ES and the SHARP EL-W516. It's a user manual in PDF format for both calculators, as well as a comparison of their capabilities. I'm posting a link to it here, hoping for some feedback - it's not 100% complete but very close to it. Volume One and Volume Two are now available for download from my account at Mediafire. The cost is of course free. Volume Two is an Appendix and some supplementary material. Thanks!

The names of the files right now are CasioSharp_Vol_1.pdf and CasioSharp_Vol_2.pdf

There's a green download button at the bottom of this page of my website which will direct you to my Mediafire download page.

You may also go directly to my mediafire account for the download. Just click the name CasioSharp.pdf to download the PDF file.

Hi,
This seems to be a lot of work. But I can’t see the reason behind it?
Thank you.

Well, not that much work - it was done over time. For those who already own and like their Casio or Sharp scientifics, and know how to use them, there is no reason to read another set of manuals. My work was meant for those who are trying to choose between the Sharp EL-W516 and Casio fx-115ES - or - for those who own one calculator or the other and want to learn more on how to use it. Both these calculators are unique in that they cost about 20 US Dollars and are able to work with matrices, vectors, complex numbers, and simultaneous equation solving. Take a look at some posts and you'll see many basic questions... "how do I enter a vector?", "how do I multiply matrices?", or "how do I find complex solutions?". The manuals that come with the calculators give button presses but no explanations, and so many people don't get much out of reading the manuals. I tried to supply some math background, walkthroughs for selected solutions, and a comparison between the operation of the two calculators. It might help someone, just starting out, if they are given more explanation. You are correct though. For most of us here who are already well practiced, my PDF's are just an alternate reference.
