The Olympia LCD 1110 calculator features a 10-digit LCD display. All calculation results are quickly and easily readable. It is solar-powered but has an additional backup battery in case the sunlight does not sufficiently charge the battery. The calculator has a metal casing. The keys are made of rubber and are very easy to operate. In addition to basic arithmetic operations, the Olympia calculator also handles percentage and square root calculations. It also includes a memory function and an automatic shut-off feature that ensures the calculator turns off after a prolonged period of inactivity.
