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!

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.
