Designed Around Daily Learning

A calculator should make learning easier, not more complicated.

The clear natural display presents supported fractions, roots and mathematical expressions in a format that feels familiar when compared with textbooks and classroom notes. This helps reduce confusion when following examples or checking calculations during lessons.

The four-line display provides a more organised viewing experience, making it easier to review values and compare different calculation steps while studying.

Learn, Review and Correct with Confidence

Making mistakes is a normal part of learning.

The built-in Multi-Replay function allows you to move back through previous calculations, review earlier entries and correct individual numbers or symbols without typing the entire equation again.

This simple feature can save valuable study time and encourages students to check their work more carefully before moving on to the next question.

Reliable Wherever You Study

The calculator combines solar-assisted operation with a replaceable button battery, giving dependable performance in classrooms, libraries, study rooms and at home.

When sufficient light is available, the solar panel helps support operation. In lower-light environments, the backup battery continues supplying power, helping reduce interruptions while studying.

Automatic power-off also helps conserve battery life when the calculator is not being used.

Built for Everyday Student Life

Students carry calculators almost everywhere, so durability matters just as much as performance.

The slim body fits neatly into school bags, backpacks and laptop sleeves without taking up unnecessary space. The included sliding protective cover helps protect the screen and keypad from scratches during daily transport.

Responsive plastic keys with clearly printed symbols provide comfortable operation for both short calculations and longer study sessions.
