I know from experience that Open University maths exams do not allow calculators that can evaluate integrals so, in that case, this would not be allowed. I would ask the faculty what calculators are permissible in exams as this might also depend on the module, as well as the institution. **Q: Does this calculator have a linear regression function?** A: Yes. A quick search on youtube for LG produced results. Good luck! **Q: Does this have CAS?** A: No this calculator does not have CAS. CAS stands for "Computer Algebra System", which means that calculators with this do symbolic algebra. This is why CAS calculators are banned in most exams. **Q: Does it have graphical computing capabilities? I need to take a math test, the calculator is not allowed to graph calculation function.** A: No but it will work out tables of values for you. ## Frequently Bought Together - Casio fx-991CW Advanced Scientific Calculator (UK Version) - Helix Oxford Maths Set with Storage Tin - 10 Piece Maths Equipment Set - Zamasha Clear Pencil Case Black | 22x4x9 cm Stylish, Practical and Transparent Pencil Case | Versatile Storage for Stationery, Toiletries, Makeup, Travel & Office Supplies --- ## 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.hu/products/516361960-casio-fx-991cw-advanced-scientific-calculator-uk-version](https://www.desertcart.hu/products/516361960-casio-fx-991cw-advanced-scientific-calculator-uk-version) --- *Product available on Desertcart Hungary* *Store origin: HU* *Last updated: 2026-05-13*
