PROBLEM TO BE SOLVED: To provide a device for formula calculation which enables formula display by adding a postposing function input for the displayed calculation result, even if it is the past calculation result displayed as a calculation history. SOLUTION: When multi-replay data including a past input formula (e.g. [3/8+1/8]) and each result recorded in a multi-replay data memory 17a, are read one by one, and a formula including the postposing function (e.g. a reduction function [simp]) is input in a state where an optional input formula (e.g., [3/8+1/8]) and its calculation result [4/8] are displayed on a display part 19; a new formula [4/8→Simp (downward arrow)] to which an input formula of the postposing function [simp] is added to the calculation result [4/8] which have been displayed immediately before is displayed on the display part 19, and becomes calculation executable by calculation of "an calculation key" 18c.
