"What numbers did I input?” "Was the number I input correct?” Everyone must have caught on such anxiety while using a calculator. SmartCalc is a calculator that wipes out such anxiety. Because, after a calculation, inputs are displayed as you input, and also one input number can be changed for the next calculation. [Instructions] • To recall calculation history, tap "< Prev" key until you find the history you want. After you tapped "< Prev" key, if you want to recall a newer history, tap "Next >" key until you find it. • To clear the calculator completely including calculation history, close SmartCalc. • To clear the calculator except for the set memory and the independent memory on MR-line, tap "C" key and then tap "AC" key appeared, that is, double tap "C" key. • To clear the independent memory on MR-line, tap "MR" key and then tap "MC" key appeared, or swipe on MR-line. • To completely clear the number you have just input on 1st-line or 2nd-line, tap "C" key. • To erase a right end number at 1st-line or 2nd-line framed in the input mode, swipe on the line. • To change one of input numbers after a calculation, please tap the input line display to input a new number. • Tapping Result-line display is a convenient substitute for tapping "=" key. [Features] • SmartCalc is a calculator with a large 4-line display, which consists of 1st-line, 2nd-line, Result-line and MR-line.

Anyone can use SmartCalc easily. • SmartCalc equips the set memory in addition to the general independent memory.
