## 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.
