NumWorks Graphing Calculator - Advanced Math Tool for Students and Professionals

lumachel: il était impératif d'avoir cette calculatrice pour ma fille lycéenne. Donc à part dire que le prix sur amazon est compétitif il est difficile de faire une évaluation à part dire que c'est l'une des calculatrices scientifiques les moins chères du marché. La batterie tient très longtemps. Pas de mises à jour à faire 2 mois après la rentrée scolaire

AlanTech67: J'ai du commander cette calculatrice pour mon BTS vu que mon prof de Maths souhaite utiliser cette calculatrice et non la casio que j'avais.
Le prix semble raisonnable on va dire ça !

Tiriplic: Conforme à la déscription. Ma fille s'en sert tous les jours. Et cela se transmettra probablement à la prochaine génération.

Alec: As a long-time user of graphing calculators and teacher of maths at IB Higher level/AP/A-level I can say without doubt that this is the best calculator for any pre-university maths course. I own and use Ti 84s, Ti Nspires, Casio FX-CG50s and have used the HP Prime in emulator form, and finding this calculator has been a breath of fresh air. It is so much easier to pick up and learn to use, more powerful, more flexible, and overall better thought out than the exam board accepted alternatives. It's lightning fast and significantly cheaper than the Ti/Casio/HP alternatives.

Best of all you can try before you buy! There is a free emulator app that you can use on your phone, iPad, or computer. I used it for a good year and a half on my phone before I bought the physical calculator as I could no longer justify being a bad example to my students and constantly getting my phone out in class.

If you need a graphing calculator for your maths course then get this one. You'll save at least £30 on the competition and find your life easier. If you currently are using an alternative and possibly finding it tricky to learn (looking at you Ti 84, looking at you...) then download the...

Josh R: I love this calculator and it makes me sad to not be giving it 5 stars. The interface is extremely streamlined and easy to use. It makes longer calculations easy to check for mistakes at a glace, compared to a Ti-84, and it simplifies matrix and statistics calculations beautifully. The use of this calculator is extremely intuitive, and does not require memorization of commands and methods like other graphing calculators require.

But it crashes all the time! The screen goes dark and you have to press the reset button on the back to get it working again, which prompts you to enter your language again country again. It also reverts all your settings to factory default, which is very frustrating especially during a test. It could be very easy to frantically reset this calculator, not realize you've switched from degrees to radians, and submit incorrect calculations.

That being said, even with the crashes, this has replaced my outdated Ti-84. I really do believe the way this calculator has simplified the clunky interface that the Ti-84 offers is the next best step forward, and it offers a much needed and overdue update for graphing calculators in the 21st century.

Chauncey: I am writing on behalf of my math teacher who is concerned because I have spent a lot of money on this defective product. When my NumWorks calculator is plugged in, it does not always charge and powers itself off a lot of the time. I went to the NumWorks website and updated it recently after I bought it but it was not effective and still seemed to not work right. After charging the calculator, it only lasts for around an hour before it dies all over again. This is very frustrating because I can never fully rely on this calculator. I am disappointed with the product I received and wish that I was sent a NumWorks that worked properly.

jejo13: My daughter really likes this calculator for her math class. She says it’s less clicks to do the same thing as the competing brand and she loves the color screen. She says it’s easier to read.

Amazon Customer: The media could not be loaded.  Pros:
More updated interface than the TI-84
Simple to use
Open source hardware
Epsilon (the calculator's "OS" (more like a math interpreter) is open source
Thin and light
Costs less than the TI-84 plus ce
Less confusing naming scheme than TI
Uses a more updated chip than the TI-84 Plus CE (STM32 ARM Cortex M4 based microcontroller vs Zialog eZ80)
Runs MicroPython (which is good for running custom code on the calculator, like a stoicheometry calculator for chemistry)
Web-based interface on computer that allows you to update the calculator and upload python code
Clean design
App-based interface
It doesn't just give decimals and fractions, it gives both, and can simplify expressions
Can calculate complex numbers

Cons:
No dark mode (Small complaint though (and it wouldn't fit in with the white theme of the calculator)
Cannot write custom apps or install custom firmware. I found this out when I was trying to add an overclocking script. I got everything set up, but a critical folder on GitHub was blocked off. This does make sense because it prevents people from writing cheating software for the...
