NEWYES 991ES Plus Scientific Calculator with Writing Tablet, 417 Function with Solar Battery, Professional Upgraded 991ES Plus Calculator Portable Notepad Back to School Supplies for Student, Teacher

Great little calculator .. As described .

Surprisingly useful calculator for A-Level, Engineering etc. The stylus-notepad is fun, useful and conveniently easy to use. The calculator is a standard scientific, broadly in line with the old workhorse Casio fx-991EX. Under the MODE menu we have: 1. COMP 2, CMPLX 3. STAT (1 variable and 2-Variable Regression of all kinds) 4. BASE-N (DEC, HEX, BIN, OCT; includes logic functions e.g. XNOR, NEG) 5. EQN (Up to cubics; others available via the SOLVE function) 6. MATRIX (Up to three 3 x 3) 7. TABLE (Single function f(x) only) 8. VECTOR (2-dim or 3-dim with dot and cross product) Good to have the functions accessible via buttons rather than deep menus. Factorial, nCr and nPr for example, are accessible using only the SHIFT key. The very useful ":" multi-statement button enables you to show a sequence of calculations with successive presses of the = button, and the ANS key adds another layer of useful recursion. Numerical differentiation and integration work fine, and there's a Sigma template for summing single-variable functions over a given range. All in all, good value for money and the folder stylus pad makes the most useful calculator cover out there.

Functionally, amazing. Has all the features you'd expect and possibly some you hadn't thought about. One frustrating feature is 'it rocks' when I try to write on the screen. The hinges aren't central and the screen sits about 3mm high. When I put weight on the screen (RHS) the left hand side lifts up.

Honestly this calculator is so good for assignments when I don't want to get a book and pen out I will say its a bit expensive but it's easy to use and perfect for my needs

it is really good quality my daughter loves that she can write on the screen, but apparently she is not allowed to use it when she does her GCSE exam, not sure about other schools. overall it's really good and easy to use.

very nice

Easy to use. But writing board broke down after uses 2 times, even changed battery still no works. Quality no good.

Highly recommend! The product does work took me some tinkering to understand how to use it but once you’ve done it it’s done so it’s a pretty decent ease of use calculator. The buttons feel of goood quality if it matters much to with no too much wiggle and instead feeling premium and nice to the touch. There are cheaper but do they have an erasable drawing pad?

Pas de mode examen. Sinon le produit est super.

Great little calculator, it’s slim and compact. The drawing pad is nice for doing chains on or just doodling on. It’s a fast charge too ! Perfect for all my math needs.

It is a bit expensive for a calculator BUT i love it! This more expensive one has a prettier color and has a prettier look than the cheaper ones. This one also has a rounder and smaller pen than the others. Have had it for many months and havent had to charge it once (i work inside so its not the sun recharging). But just for anyone who DOES buy this, it starts out only being able to do fraction not decimals. You have to get it to "stat" mode. Press on>mode>3. Thats what worked for me to turn it, since i need decimals for work.

Trés bien. Contente de mon achat pour ma fille en 2nde.
