Easy Math By Sparkle333 on Feb 06, 2009 - Updated Oct 15, 2011

Since I have a collectibles booth in an indoor flea market, I have to tag a lot of merchandise. I have to figure how much items cost me with sales tax, as well as decide what a profitable markup would be. That's when it's nice to have a handy calculator that can help me with these tasks. I also need it to be portable, so that I can work on it in my booth, as well as at home.

So I found this great medium-sized Casio Calculator with an extra large, easy to read display. It features an independent memory, easy tax calculations, as well as a conversion mode, and a memory mode. It features 2- way power, with both solar cell and a button battery back-up. It automatically switches off when six minutes without key operation have occurred.

I only need it for basic math calculations, and will probably never get to experience all of its great features. It does have a limited warranty, and technical support is also available. I am sure that I will enjoy using my new Casio calculator, as math has never been one of my strong points. So the easier the better!
