This particular calculator has a metal and plastic case and thirty-nine rectangular plastic keys. The four lower rows of keys are similar to those found on many calculators, with ten digit keys, a change sign key, a decimal point key, four arithmetic function keys, three memory keys and a total key. The memory keys also can serve as keys for various statistical functions, as can two keys above them. The remaining keys represent a wide array of trigonometric, logarithmic, exponential and other functions, as well as a function key and an on/clear key. Above the keys is an on/off switch. A mark next to it reads: SHARP (/) Scientific calculator (/) EL-506. Behind this is a ten-digit LCD display.
