The problem is the instruction booklet does not go with the calculator. Keys mentioned in the booklet are not present on the actual calculator and that includes buttons necessary for mean and SD calculations. I have spent a lot of time on this calculator and so far have not been bale to get mean or SD. The Chinese manufacturers need to produce an instruction booklet that refers to the particular calculator in question. As it is I cannot recommend this calculator. **Q: How do you change it to radian mode?** A: Press the key Mode/clr key several times until DEG RAD GRA appears. Then press the number under the word RAD. **Q: I have a function question. if i want to square root 9, do i input 9 1st, or do i select the square root function 1st?** A: Select the square root function first. **Q: can you actually see the parentheses when you press it** A: Yes. ## Frequently Bought Together - Helect 2-Line Engineering Scientific Calculator, Suitable for School and Business (Black) - BIC Brite Liner Highlighters, Chisel Tip, 5-Count Pack of Highlighters Assorted Colors, Ideal Highlighter Set for Organizing and Coloring - BIC Xtra-Life Mechanical Pencil, Clear Barrel, Medium Point (0.7mm), 10-Count, Packaging May Vary --- ## 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.tn/products/44215738-helect-2-line-engineering-scientific-calculator-suitable-for-school-business](https://www.desertcart.tn/products/44215738-helect-2-line-engineering-scientific-calculator-suitable-for-school-business) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-07*
