摘要
An electronic computer of the invention adopts prefix unary operators, so that key operation for entering arithmetic or mathematical expressions is performed in the normal order of the operands and operators of the expression, and moreover the last calculation result can be directly used as the operand for the prefix unary operator. Therefore, sequential calculations can be performed step by step while checking the intermediate results by simple key operation.
