Casio FX-991 EX Wetenschappelijke rekenmachine met 552 functies, zwart-wit, 1,02 x 16,51 x 7,62 cm, 90,72 gram

Studeer je elektrotechniek? Koop dit apparaat!Deze rekenmachine is toegestaan op de tentamens, omdat het geen grafische rekenmachine is.Wel heeft de rekenmachine de functionaliteit om matrices te vermenigvuldigen, bepaalde integralen te berekenen, a+bj en modulus hoek notatie en ga zo maar door.Het scherm heeft een hoge resolutie en is goed leesbaar, zie geen redenen om deze rekenmachine niet te kopen.

cheap quatity

The product works and its easy to operate, came on time

If you are looking for a calculator similar to a graphing calculator such as TI-84 plus, this is the one you should opt for. It is not a graphing calculator though it has so many good features that a typical scientific calculator does not have

Since im a science major, but it's a good thing to have regardless.

All good, product working great

Lots of functionality and easy to use. The combination of battery and solar is welcome as well.Great for kids and adults.

I saw a review saying that it's not genuine so I was a little worried. But don't worry, I can assure you that it was 100% genuine, I did the authenticity checks with the QR code generation and checking the battery compartment.This costs the same as the fx-97SG you can get at Popular but with way more functions! You have logarithms with customisable bases, stored numerical constants, a series generator, differential and integral calculator, prime factor decomposition, solving for x and many more. If you are an engineering student this is the perfect calculator for you. It will save your butt during your exams because you can directly obtain your answer from the calculator so you'll be able to spot any careless mistakes in your working.

Difficult to find this product on Amazon and was concerned a different model would be delivered but it came on time and was accurate!

has been using for years and still works great. My bestie for math and sciences since high school and I am almost gradfuating university now. Recommended!

Muy bueno el producto, llego muy rápido.
