PURPOSE:To easily understand the resolution of simultaneous equations by displaying each step of the resolution of the simultaneous equations in accordance with a keyed known numerical data every depression of a step resolution key. CONSTITUTION:A key entry part 11 is provided with ten keys 11a for inputting numeral data, a function key 11b for inputting function data, a store key 11c for commanding the substitution of known numerical data, keys A-<= 11d-11f for substituting known nemerical data (a)-(c), keys D-F 11g-11i for substituting known numerical data (d)-(f), and a step resolution key 11j for commanding the display of step-like resolution of dual-linear simultaneous equation. An arithmetic part 13 writes or read out data in/form respective registers 14a-14h of a register part 14 on the basis of control data obtained from a control part 12 to execute operation and sends the data to be displayed on a display register 15, so that the resolution of the simultaneous equations is displayed on a display part 16. Consequently, the resolution of the simultaneous equations can be easily understood.
