The Sharp EL243S is a handheld calculator that combines functionality, convenience and reliability for everyday use. Its extra-large 8-digit LCD uses 13.5 mm characters with punctuation, which is unusually generous for a calculator this size and makes it readable at arm's length rather than only up close. The display sits on a slant so it can be read while the calculator lies flat on a desk. A three-key memory holds a running value alongside the main calculation, and twin power runs it on solar energy with battery backup so it works in poor light without stalling. A protective cover shields the LCD and keypad in a bag, drawer or pocket between uses.
