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. ## Frequently Bought Together - Casio fx-260 Solar II Scientific Calculator | 10-Digit Display | Fraction & Trig Functions | Ideal for Middle School, High School Math, Algebra, Trigonometry | Solar Powered - Texas Instruments TI-30XIIS Scientific Calculator, Black with Blue Accents - Casio SL-300SV Standard Function Desktop Calculator | General Purpose | Large 8-Digit Display | Pocket Size | Basic Math Functions| Ideal for Home & Office --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ec/products/42533216-fx-260-solar-ii-scientific-calculator-10-digit-display](https://www.desertcart.ec/products/42533216-fx-260-solar-ii-scientific-calculator-10-digit-display) --- *Product available on Desertcart Ecuador* *Store origin: EC* *Last updated: 2026-09-16*
