417 Functions for Everyday and Advanced Mathematics
A basic calculator may be enough for simple sums, but it quickly becomes limiting when schoolwork or office calculations become more demanding.
This scientific calculator supports a broad selection of functions, including:
General arithmetic
Fraction calculations
Powers, roots and logarithms
Trigonometric calculations
Statistical calculations
Complex-number calculations
Matrix calculations
Vector calculations
Equation mode
Table mode
The range of functions makes it a practical study companion for mathematics, science, engineering-related coursework and everyday numerical work.
Eight Calculation Modes in One Device
Use the mode menu to select the type of calculation required:
- COMP - General calculations
- CMPLX - Complex-number calculations
- STAT - Statistical calculations
- BASE-N - Number-base calculations
- EQN - Equation calculations
- MATRIX - Matrix calculations
- TABLE - Function table calculations
- VECTOR - Vector calculations
Instead of changing between several calculators, one device keeps different calculation tools available in a familiar layout.
Textbook-Style Display for Easier Reading
Long expressions can become confusing when every symbol appears in a single compressed line.
The clear LCD screen displays fractions, roots and mathematical expressions in a more natural textbook-style layout, helping equations look closer to the way they appear in study notes and textbooks.
This makes it easier to:
Enter formulas accurately
Follow longer expressions
Check fractions and symbols
Read results comfortably
Reduce input mistakes
Multi-Replay Helps You Review Your Work
Made an input error or want to check an earlier calculation?
The central replay control allows you to move through previous steps and review entered expressions without starting everything again.
This is especially useful when working through longer equations, statistics exercises or multi-step homework problems.
List-Based Statistics and Fraction Calculations
The calculator supports organised statistical data entry, helping users work with lists and view calculation results more efficiently.
Fractions can also be entered and displayed in a familiar mathematical format, making the calculator useful for classroom exercises, homework and revision.
Dual Power for Reliable Daily Use
The two-way power system combines solar assistance with a replaceable button battery, helping the calculator remain ready for everyday study and office use.
An automatic power-off function helps reduce unnecessary battery use when the calculator is left inactive.
Actual battery life varies according to usage frequency and operating conditions.
Responsive Keys with a Clear Layout
A calculator may offer many functions, but it still needs to feel comfortable during regular use.
The clearly marked plastic keys are designed for responsive input, while the colour-coded secondary functions help users identify important controls more easily.
The dedicated navigation, delete and clear buttons also make formula entry and correction more convenient.
Sliding Cover for Storage and Protection
The included sliding cover helps protect the calculator body, display and buttons while it is stored inside a backpack, school bag, desk drawer or office case.
The thickened protective shell, wear-resistant construction and non-slip feet provide additional support for everyday handling and desktop use.
The cover also includes a printed reference guide for convenient access to selected formulas and conversions.
Compact Enough for Study Anywhere
Measuring approximately 155 × 80 × 15mm, the calculator is easy to hold, store and carry.
Suitable for:
School mathematics and science
University coursework
Homework and revision
Tutoring sessions
Office calculations
Home study
Everyday numerical tasks
