Casio fx-991ES Plus 2 Scientific Calculator with 417 Functions and Display, Natural

Got this for my daughter who needed it in college for chemistry classes. She said it works great! Would recommend.

Útil para colegio

I do electronics engineering and I always need to calculate semi-complex stuff. A non scientific calculator is a pain and I find that the ti-84 is a bit much if you’re not doing advanced math or statistics. This calculator is perfect for the bench calculations while designing circuits. Plus because it’s not a small fortune, I carry it around all the time without worry of dropping it etc. my colleagues call me Egon now because I just pull out the calculator and start calculating in random situations and conversations. For the price, you really can’t go wrong.

Good for school

I love it i git what I want easy to use specifically for FE Preparation

Perfect 👌

My kid says it works great! The price wasn't too bad either. My child was able to find and use all the functions a bit easier than other scientific calculators before. The box did come in a bit beat up but all good so far.

Exactly as in the picture

Si estás buscando una calculadora científica completa y fiable, esta es la mejor opción del mercado. Tiene tapa protectora, ideal para llevarla sin preocuparte por golpes o arañazos. Además, al ser Casio, viene con la garantía de calidad de una marca de confianza. Lo que más me ha gustado es su función de notación natural: las operaciones y fracciones se ven igual que en los libros, lo que facilita muchísimo el trabajo y evita errores al interpretar resultados. Es rápida, precisa y muy intuitiva. En resumen, una calculadora inmejorable para estudiantes de secundaria, bachillerato e incluso universidad. ¡Un acierto total!

Bardzo dobry - kupiłem dla syna studenta - zachwycony

Excellent

Great calculator compact durable has all the functions you ever need would recommend

Five stars, since it is a decent, and affordable calculator for highschoolers. Personally, I was looking for something more, but this got pretty much the essentials; - binary/octal/decimal/hexadecimal conversions - imaginary numbers - summation - decent display utilising a matrix dot display. I am a bit disappointed with how it does seem clunky to use at times, and the interface is rather inconsistent. (eg. ×10ⁿ being one unit / seperate) Furthermore, other modes feel... limited.
