This specific model of calculator is often selected by educators for classroom use due to its combination of functionality and affordability. It provides sufficient capabilities for middle and high school mathematics, including algebra, geometry, trigonometry, and statistics, while remaining simple enough for students to learn quickly. For example, its fraction capabilities and two-line display make it easier for students to work with complex calculations.
The choice of this particular device as the standard in many educational settings stems from its balance between features and cost-effectiveness. This allows schools to equip classrooms without excessive expenditure, while still providing students with the tools they need for success in mathematics courses. This widespread adoption has led to a wealth of readily available teaching resources and support materials specifically designed for this model, further solidifying its place in the classroom. Its long history in the educational market also contributes to this established position.
