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

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. COMP2, CMPLX3. 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.

Got this for my son has had it for 2 years works amazing definitely worth buying it

Needed this for a course in short notice whilst working away from home. No complaints at all.

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?

Using for engineering HNC, has all the required functions and whilst I thought the writing pad was rather gimiky, I've found it to be very helpful for note taking, I'm able to write my full equations and calculte with the correct showing on screen at the same time and then take a photo with my phone for later revision.Downside is a rather cheap feel, but considering the functions its pretty good

I am very happy with it. The note pad is great. I have similar like this and one thing is not good for both of them. The display is little bit hard to be reading from low angle. But everything other is perfect.

It is the same weight as any modern calculator, but strong because of cover.It feels light compared to a mobile phone, but it certainly isn't flimsy.The note pad is separate from the calculator and has an erase protect switch. Turning the calculator off does not erase the screen! Thrre is a separate button to erase screen.Calculator has some advanced functions, so reading manual is a must!Highly recommended.

Bought for grandson excellent product and he loves the board he can write on

Ya pedí dos para mis nietos iguales y aunque tengo otras no me he resistido a tener otra igual.
