The Casio fx-115ES Plus 2nd Edition is a specialized tool for advanced mathematics and engineering, frequently utilized for professional licensure exams. Tests show the exterior is made of high-impact ABS plastic, which provides structural protection against daily household or backpack use. The rear of the unit features a non-slip texture to help the device stay in place on flat surfaces during rapid data entry.
Specifications indicate that the screen uses a specialized dot-matrix display designed to remain clear at various viewing angles. This model utilizes a dual-power system, combining an LR44 battery with an integrated solar cell. This helps monitor power levels by allowing the device to operate even in low-light environments, such as a dimly lit home office or laboratory.
Practical Features and Usage
- Supports complex calculations including 4x4 matrices and vector arithmetic.
- Features a high-resolution display that shows math problems as they appear in textbooks.
- Comes with a redesigned protective slide case that adds significant rigidity for transport.
While the new slide-on case provides improved protection, it requires a firmer "snap" to secure properly compared to previous versions. Practical safety features include materials rated to resist standard heat levels, adding a layer of security for home storage. Specifications indicate the keys are designed for high-cycle use, though they may produce a more audible click than earlier models.
The dual-power system is specifically designed to provide uninterrupted service during critical tasks, reducing the risk of power loss when a solar source is unavailable.
For those who prefer a more specialized tool for younger students, the Casio fx-55PLUS provides a focused interface for learning fractions.
