摘要
Disclosed is an electronic calculator having a data entry unit for inputting numeric data, expressions such as parentheses and hierarchal mathematical commands, an arithmetic unit for performing arithmetic operations on the numeric data, a memory for storing the numeric data and associated hierarchal mathematical commands inputted via the data entry unit and logic circuitry for enabling the arithmetic unit to perform arithmetic operations on numeric data inputted via the data entry unit within a pair of parentheses, the logic circuitry enabling the arithmetic unit to perform a higher order hierarchal mathematical command before a lower order hierarchal command eventhough the higher order command is received after the lower order hierarchal mathematical command.
