252 scientific, statistical, and trigonometric functions; solar-powered for long-use without batteries; natural display that shows expressions as in textbooks; compact and lightweight design for portability; reliable accuracy for precise scientific calculations.

Natural Display shows fractions, roots, and equations exactly as they appear in textbooks, making it easier to verify steps and reduce entry errors during calculations.

You can perform algebraic expressions, trigonometric functions, logarithms, exponentials, fractions, roots, statistics, and other standard scientific calculations.

Ideal for math, physics, engineering, statistics, and general STEM coursework, exam prep, and on-the-go problem solving in labs and study sessions.

Power on the calculator in a well-lit area, set your preferred angle unit (degrees or radians), and use the mode and function keys to access scientific and statistical features. Keep the solar panel exposed to light to maintain power.

Use the mode selector to switch to the scientific/statistics functions, then use the corresponding keys (and any necessary secondary functions accessed via SHIFT/SECOND function) to perform advanced calculations such as regression, standard deviation, and trigonometric calculations.

Yes. It is a non-CAS scientific calculator suitable for many classrooms and exams, with a design focused on reliability and accuracy while remaining compact and user-friendly.
