Casio Scientific Calculator With 417 Functions, 2Nd Edition - Black

It includes 417 functions across categories such as scientific calculations, statistics, fractions, algebra, trigonometry, logarithms, and complex numbers, enabling a wide range of computations in one device.

Natural Display shows equations and expressions in textbook-style formatting, so you can read and verify inputs and results the way they appear in your coursework.

Yes, it is solar-powered with a battery back-up. The solar panel provides energy under light, while the back-up battery ensures continued operation in low-light conditions.

The multi-line display lets you view multiple lines of calculations simultaneously, so you can see inputs, intermediate steps, and results side by side to improve accuracy and workflow.

Ideal for STEM coursework, engineering problems, statistical analysis, data interpretation, exam preparation, and any scenario requiring reliable scientific calculations with many built-in functions.

Enter data into the statistics mode (often via the MODE button), choose the one- or two-variable statistics option, input your data set, and use the statistics functions to compute mean, standard deviation, regression, and probabilities.

Use the trig keys (sin, cos, tan) with your angle unit set (degrees or radians). For logarithms, use log and ln keys, and combine with exponent and power functions as needed.

Use the MODE or SHIFT (SHFT) key to access secondary functions. The SHFT functions are printed above the keys, and MODE lets you switch between calculation modes (e.g., degrees/radians, statistics, etc.).

It is widely used in STEM exams that permit non-CAS scientific calculators. Always verify your specific exam's calculator policy to ensure compliance with allowed features.

The calculator features a sturdy build designed for regular classroom and field use. To care for it, keep it dry, clean with a soft cloth, and avoid exposing it to heavy impact or moisture.

Compared to the Casio FX991EX ClassWiz, the FX991EX typically offers more advanced features and a higher-resolution display, while still covering core scientific and statistical functions. The FX115ES Plus provides a similar scientific feature set at a potentially lower price, with a more traditional layout.
