Expression and signs, such as a mathematics natural display fraction and root, can be displayed as a textbook. Moreover, a calculation result can be displayed by expression containing a fraction and root. The statistical data edit-function statistical data of a list base can be intelligibly inputted in the form of a table, and it can use for statistic calculation. By adoption of the full dot system display excellent in legible full dot display visibility, a fraction, logarithm, and the expression and the sign of root can be displayed as a textbook. By sliding the center cursor key parameter of easy operation up and down, four-directions movement in a formula can be performed easily. Moreover, the multi-Ripley function which calls and corrects the formula performed once and can be performed again is carried. It is convenient for the repetitive calculation etc. Which replace a numerical value. By a multi-replay center cursor key, four-directions movement of a formula can be performed easily. Calculate f(x) value over x value and display table operation function expression f(x) by list. Key operation is only carried out as the formula currently written on the input method textbook as the form, and it can input
