The Casio FX-991ESPLUS has long been a staple in classrooms and offices alike, known for its reliability and comprehensive feature set.

The FX-991ESPLUS Pink boasts a range of features designed for efficiency and accuracy. The standout feature is undoubtedly the built-in tax calculation function. This is incredibly helpful for anyone working with finances, allowing for quick and precise calculations of taxes, discounts, and markups. The large, interactive display is another significant improvement over previous models. Numbers are crisp and easy to read, even in dimly lit environments. Navigation is intuitive and straightforward, even for those unfamiliar with the calculator’s extensive capabilities. Beyond the tax functions, the FX-991ESPLUS offers a comprehensive suite of scientific functions, making it suitable for a wide variety of applications, from basic arithmetic to complex calculations involving logarithms, trigonometry, and statistics.

The large display is also a boon to usability, significantly reducing eye strain during prolonged use. The buttons have a satisfying tactile response, further enhancing the user experience.
