Review: Great calculator at an affordable price! - This is, without a doubt, one of the best 'science and day-to-day' calculators you could ask for! It is compact in size, full function...from polar-to-rectangular, statistics, squares and cubes, nesting, and so much more. It is a 'dual-power' calculator, so the calculator can be used in total darkness (LR-44 battery required), though the solar cell will easily power it in any office lighting at night. The cell DOES NOT charge the battery, but Casio claims 3-years of use from one battery (using it one hour per day). It has a 'slider cover shell' to protect the calculator while in your pocket, too...and it 'bites' quite well...no falling off here. I purchased this after the Casio fx-82sx finally 'gave up the ghost' (with the markings worn off, keys chipped...the screen finally died). I wish Casio still made the fx-82sx still, but since they don't...guess the fx-260 solar is close enough. SOLID 5-stars, as most Casio products are! Definitely recommend!
Review: School recommended! - This calculator was school recommended for our middle school- it seems to do the job! Good quality, my son says it’s a nice calculator!

## Questions & Answers

**Q: Does this calculator support dual mode(have backup battery)?**
A: I'm looking for a "solar only" (no auto-shutoff) calculator, but the description on this one says "2 AA batteries required." -- maybe seller can answer?

**Q: what are the dimensions in inches?**
A: I use these for my Compassion Boxes (Samaritans Purse), have them already packed up, but I can assure you they are a just right size maybe approximately 3 x 5". Very solid and solar is why I buy them, so they don't need continual batteries, which these children do not have access to. That is the best I can do for you! I just noticed it says 3" x 5" 2.25 (FX-260 SolarII-SIH) This should answer your question for sure!

**Q: Does this have statistical functions?**
A: It has the basic stats functions, such as sample and population average, standard deviation, etc. It's been decades since I studied stats, but the FX-260 SolarII has the basics stats functions, yes.

**Q: First I need a calculator that can do fractions. (Into fractions) It says it's a solar powered but product description says batteries?**
A: This item should have the ability to calculate fractions during the SHIFT mode. This item is solar powered and does not need batteries.

*by M***! on January 13, 2026*

This calculator was school recommended for our middle school- it seems to do the job! Good quality, my son says it’s a nice calculator!

### ⭐⭐⭐⭐⭐ Extremely Handy. I would buy again if needed
*by J***S on August 17, 2025*

I love the fact that this calculator is solar powered. Since you are not likely to use this in the dark it is very convenient to never have to be concerned about whether or not the battery is charged. i have had one of these for quite a few years and it has never failed yet. The only drawback for me is that I used calculators from HP with Reverse Polish Notation rather than algebraic entry for over 40 years and it takes a lot of getting used to. But I know most people don't have that issue so this is a really good calculator for not much money.
