It easy use, the display is clear and easy to read . The size is ok for hand held. It works for easy to advance calculations. It look likes its built to last for long time.. I highly recommend to students and who need a dependab calculator.. ### ⭐⭐⭐⭐⭐ Easy to use Calculator *by W***E on April 28, 2026* Takes a little getting used to at first, but it becomes easy with practice. Like most Casio products, it’s reliable and packed with useful functions. The solar and battery power option is a big plus. ### ⭐⭐⭐⭐⭐ Bold, clear display, familiar Casio scientific calculator layout *by J***N on May 19, 2025* This is a fantastic calculator with the usual Casio layout. I can read the display clearly in any lighting conditions (well, except for a very dark room), making it excellent for use outdoors or in a dim room. Numbers aren't as large as on most basic calculators, but their boldness and excellent contrast ensures they are just as legible. If your trusty fx-115MS finally died on you, this is as close as it gets to a direct replacement. Do NOT spring for the current fx-115ES unless you work in a well-lit office environment. I mainly use my calculator to work out angles and dimensions for woodworking and 3D modeling (at home) and machining (at work). I don't know how sturdy or dust-proof it is, but I absolutely trust it over my fragile, expensive smartphone to have in a work environment. Or any environment. I can't stand touch screens. Speaking of which...you may struggle to use this calculator with thick leather gloves, but with skinnier mechanic-type gloves you shouldn't have any issues. Spacing for the main number keys is 1/2" x 7/16" (13mm x 11mm) and spacing for the smaller keys in the upper block is 7/16" x 3/8" (11mm x 9mm). Definitely not as big as a basic calculator's keypad, but it's been perfectly fine for me. ## Frequently Bought Together - Casio fx-300MS Plus 2nd Edition – Standard Scientific Calculator with 2-Line Display | 10-Digit LCD, Trig, Stats, Fractions | Ideal for High School Algebra, Trigonometry & Test Prep - Casio fx-300ES Plus 2nd Edition – Standard Scientific Calculator | 262 Functions, Natural Textbook Display℠ | Ideal for Middle School, High School Math, Statistics & Algebra | Black - Texas Instruments TI-30XIIS Scientific Calculator, Black with Blue Accents --- ## 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.pt/products/638120088-fx-300ms-plus-2nd-edition-standard-scientific-calculator-with-2](https://www.desertcart.pt/products/638120088-fx-300ms-plus-2nd-edition-standard-scientific-calculator-with-2) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-06-23*
