| ALGEBRAIC OPERATING SYSTEM | |||
| Algebraic expressions can be entered just as they are written. A predetermined priority level exists which first calculates high priority then low priority operators. (eg: Multiplication and division completed prior to addition and subtraction ie: 4+6 X 4 = 28) | |||
| ADDING MACHINE OPERATING SYSTEM | |||
| Also described as Business Machine Logic. Numbers entered need to be denoted whether they are positive or negative. | |||
| OPERATION KEY SWITCHES | |||
| Decimal point selection | |||
| Fixed | : | Results are calculated to a preselected number of decimal places. eg: 2,3 or 4, etc. in accordance with the rounding switch. |
|
| Floating (F) | : | Results are displayed and printed with no limit on decimal places except the capacity of the display. | |
| Add mode (+) | : | Decimal point placed before the last two digits on display and printout. | |
| ................. | : | No decimal point entry is needed therefore suitable for currency and cash calculations. | |
| Rounding Selection | |||
| Rounding Off (5/4) | : | Results of multiplication and division rounded to a whole number. eg. 2.4 = 2 and 2.5 =3. |
|
| Rounding Down (5/4) | : | Result reduced to the nearest whole number. eg. 2.6 = 2 |
|
| Rounding Up (5/4) | : | Result increased to the nearest whole number. eg. 2.2 = 3 |
|
| Item Count | |||
| Item | : | Each addition and subtraction entry is counted and printed on left side of the paper roll. | |
| Average | |||
| Ave | : | Totals the number of items entered in addition calculations by a manual constant. | |
| Accumulation | |||
| AM | : | Entries or results automatically accumulated in the first memory. | |
| Sum OPE | : | Sum operand feature automatically accumulates multiplication entries in 2nd memory and the results in 1st memory. | |
| Constant | |||
| K | : | Perform multiplication and division calculations by a manual constant. | |
| Business Sales Calculation | |||
| Business : | Results are calculated to cost, selling price or profit margin amount. eg. 100 COST 200 SELL = 50 MARGIN % |
||
| Tax Calculation | |||
| Tax : | Perform tax calculation. | ||
| Currency Conversion Calculation | |||
| Convert : | Perform currency conversion and also metric convertor if the corresponding rate is registered. | ||
| Check Calculation | |||
| Check : | Reviews the steps of the calculations. | ||
| FUNCTION KEYS | |||
 |
Performs standard percentages along with add on or discount calculations. | ||
 |
Delta percent key calculates the actual increase / decrease and / or the percentage difference between the two numbers - also known as the increase / decrease ratio, also calculates gross profit. | ||
 |
Mark up - selling price calculated based on the cost price and profit margin percentage. | ||
| Mark down - cost price calculated from the selling price and profit (loss) margin percentage. | |||
 |
Uses for calculating the change amount, it performs accurate ad fast change calculation. | ||
 |
Perform cost, selling price and profit margin calculation. Enter to obtain the balance value item. eg. enter the value of the cost and the selling price to obtain the profit margin |
||
 |
Adds or subtract the predetermined sales tax rate (%) to / from the calculation. | ||
 |
Unit 1 - Convert currency figure displayed from Unit 2 to Unit 1. | ||
| Unit 2 - Convert currency figure displayed from Unit 1 to Unit 2. | |||
 |
Check key allows for reviewing the previous or next calculation step. | ||
 |
Correct key allows for correcting calculations contents in the Check mode. | ||
 |
Non add key allows the printing of dates, reference numbers, etc. to be printed on the left side of paper roll without affecting the calculation. | ||
 |
Sub total key allows an intermediate result of a calculation to be printed on left side of paper roll. | ||
 |
Reverse key automatically switches the operator and operand of a calculation. eg. ?8 4? changed to ?4 8? |
||
 |
Total key. | ||
| CANCEL KEYS | |||
 |
Clear indication key cancels the displayed numbers and corrects an entry as a whole. | ||
 |
Clear all key cancels all the entries and results, including memory contents. | ||
 |
Clear entry key cancels an incorrect entry. | ||
 |
Clear key cancels an incorrect entry or command and exercise must be restarted. | ||
 |
Shift key moves displayed numbers to the right thereby deleting numbers each time the key is pressed. | ||
| INDEPENDENT MEMORY KEYS | |||
| Accumulating / storing in memory | |||
 |
Results of multiplication and division automatically added to the memory. Also adds a number to the memory. | ||
 |
Results of multiplication and division automatically subtracted from to the memory. Also subtracts a number from the memory. | ||
| Recalling / clearing memory | |||
 |
Total memory. | ||
 |
Subtotals of calculations recalled without losing the contents in the memory. | ||
 |
Recalling the contents of the memory. | ||
 |
Clearing the contents of the memory (for non-printing model). | ||
