- This handheld electronic calculator is designed to fit into a checkbook (this example has no wallet). It has a plastic front, circuit board, and keys. The twenty-three rectangular keys include ten digit keys, a decimal point key (that can also serve as a memory exchange key), a percentage key (that can serve as a square root key), a total key, four arithmetic function keys (one of which can also serve as a squaring key and another as an inverse key), four memory keys, a clear entry/clear key, and a function/clear function key. The on/off switch is left of the three keys in the top row. There is space for six AAA batteries but no battery jack.
