If wrong digits are entered, press the red key [C] to clear the keyboard. ADDITION & Subtraction: ----------------------- Everytime a number is entered and the keys [+] or [-] are pressed, the number is printed and added/subtracted to/from the memory. REPEAT: ------- No "REPEAT"-Key is neccessary: The last number is held in memory and can be re-used by pressing the [+] or [-] key again. NON-ADD: -------- Enter the item number and press the key [#]. This item number is printed, but it is not part of the addition/subtraction cycle. SUBTOTAL: --------- The cumulated sum will be printed when the key [◊] is pressed. The memory will hold the actual sum. TOTAL: ------ The total sum will be printed when the key [*] is pressed. The memory will be cleared. MULTIPLICATION: --------------- Enter the multiplicant and press [x]. Enter the multiplicator and press [=]. The product will be calculated and printed. ( Examples for "Chain Multiplications" see below ... ) OVERFLOW MARKER: ---------------- When a product exceeds 12 digits, the WRONG RESULT is printed with 3 points on its left side. DIVISION: --------- Enter the divident and press [:]. Enter the divisor and press [:=]. The quotient will be calculated and printed.
