Key markings are plastic, which means they do not wear or fade with use. Keys are ergonomically shaped and configured to match natural finger movements. Solar powered when light is sufficient, battery powered when light is insufficient. Large rubber feet on the bottom of the calculator keep it from slipping during operation. A symbol ( ,−,×,÷) on the display indicates the status of the operation you are currently performing. Keys are specially designed for silent operation when compared to previous CASIO calculators to help maintain a more pleasant working environment. Key operations are stored in a buffer, so that nothing is lost even during high-speed input.
