This handheld electronic calculator has a metal and plastic case with an array of twenty-six rectangular plastic keys. These include ten digit keys, a decimal point key, a total key, four arithmetic function keys, and four memory keys. In addition there are two parenthesis keys, a square root key, a percentage key, a clear/clear entry key, an inverse key, and a squaring key. On the right side next to the two topmost keys is the on/off switch. A mark above this reads: Unisonic 1148.
