- Description
- This compact handheld electronic calculator has ten gray digit keys and a gray decimal key, four blue keys for arithmetic functions, a percentage, equals, and clear entry/clear key, and an M key to shift the keys for arithmetic functions to memory keys. Memory keys made it possible to work with subtotals and stored numbers. A red LED display for eight digits and a decimal point is behind the keyboard. The battery compartment at the top has its cover on the back. There presently is no battery and no adapter.
