Summary: The Casio FX-260 is a reliable, inexpensive compact scientific calculator with a built-in solar panel. Besides the usual functions among its 144 functions you'll find fraction calculation, random number generator, exponential multiplication, PI, and many more.
Summary: I love it. It does all I need and I am learning to love the fraction feature, as well. It is handy in remodeling projects. It has a nice slip on hard cover. I would like to see little rubber feet that keep it from sliding around on the desk as the keys are pushed.
a reasonably priced, and very capable scientific calculator...

Summary: The Casio FX-260 is a scientific calculator with a 10 digit display, and a wide range of functions. It has dual sources of power, with a photovoltaic cell, and also a backup battery. The buttons are easy to operate, laid out well, and operate positively when pushed.
Excerpt: This Casio calculator will last forever with no new batteries because the solar power really works. I know because this new purchase is my second Casio scientific instrument, very similar to the first--which still operates as well as it did when I bought it about 30 years ago.
Pros: Light/ Compact, long battery life, Good Value, Clear Display, Easy to Use, Useful Functions, Quality
