Abstract

PURPOSE:To increase the speed of calculation of a number of data with a reduced number of operations of keys, by adding a unit mode designating switch. CONSTITUTION:The unit mode switches of hundred, thousand, ten thousand and hundred million each are provided to a keyboard KB. Then an input is given throug the keyboard KB. For instance, if 2,000+3,000+4,000= is supplied in the form of 2+3+4=, the operation is carried out by a CPU to display an answer at a display part D in case the mode designating switch is set previously at the place of thousand. Furthermore 4,500 can be supplied in the form of 4.5. In such a way, a number of data can be calculated in a short time with a reduced number of operations of keys.
