The Aurora HC106 is an ideal calculator for use within primary education and specifically Key Stages 1&2. It has a clear 8 digit LCD display to enable easy viewing and is entirely solar powered so no battery is required. The calculator is designed for ease of use and has a colour coded spacious keypad and durable hard plastic keys. Also included is a slide-on hard case which protects the calculator when not in use. Overall a quality product which is very good value for money and is ideal for learning.
