In other words, the calculations are performed and the balance is always printed out. In the balance mode, the entry and balance only for addition and subtraction (by the [§ and @ key operations) can be printed out. Also, the entry is printed on the left hand side of the paper and the balance is printed with the symbol “0" on the right hand side of the paper. EXAMPLE: Entry Balance 123.00 + 123.00 456.00 + 579.00 234.00 - 345.00 Total 345.00 26 SAMPLE APPLICATIONS 1. Set the decimal selector as specified in each example. The rounding selector should be in the “5/4" position unless otherwise specified. 2. The grand total mode, constant mode, add mode, item count mode, and balance mode selectors should be in the position (off position) unless otherwise specified. 3. Print mode selector should be in the “P" position. AVERAGING (only CS-2850) Calculate the average of a series of values. SOLUTION: 1. Add the values to calculate the TOTAL VALUES, 2. Determine the NUMBER OF VALUES, FORMULA: EXAMPLE: 3. Calculate the average. Total of the values Average = Day Number of values Sales Monday .................$123.15 Tuesday..................118.00 Wednesday ...............131.58 Thursday .................125.02 Friday....................158.25 Then Total Sales $656.00 for 5 days Average Sales = $131.20 Note: If you are working in dollars and cents, use the “Add Mode.” If not, set the decimal as desired.

SOLUTION: FORMULA: EXAMPLE: 1. Calculate the quarterly interest rate. 2. Calculate the new balance (principal plus interest) New balance = P (1 + t)n Where P = amount of deposit (principal) i = interest rate per period n = number of years x 4 If P = $6,150 i = 5% annum 4 periods = 0.0125 n = 4 years x 4 periods = 16 Then 6,150 (1 + 0.0125)16 = $7,502.32 (New Balance) (1) (2) (3) (4) •05 g 0.05 0 05 4 [S 4- = 0.0125 a 0 0125 * QB 0.0125 a 0 0125 + 1 æ 1.0125 a 1- + 1 0125 O 1.0125 10125 x 3) 1-0125 = 1.02515625 a 1 02515625 * 1.02515625 1-02515625 x m 1 02515625 = 1,05094533691 a 1 05094533691 * 1.05094533691 1 05094533691 x m 1-05094533691 = 1.10448610117 a 1-10448610117 * s 1.10448610117 1-10448610117 x œ 1-10448610117 = 1.21988954767 a 1-21988954767 * 1.21988954767 1-21988954767 x 6150 [g 6-150' = 7,502.32071817 a 7-502 32071817 * -3 -1 -0 Annual int. rate Quarterly int. rate (1 +1) (1 + i)2 (1 + i)4 (1 + (1 + ¡v« Principal New balance 27 “ SPECIFICATIONS ] Type: Electronic print/display calculator Power source: AC: 120V, 60Hz Display: Fluorescent display Operating capacity: 12 digits Display/Print capacity: With symbol and 3-digit punctuations 13 digits (display), 18 digits (printing) Decimal point: Automatic decimal point positioning by preset decimal selector (0-1-2-3-4-5-6-F) with Add mode (A/+, A/x) Calculations: Four arithmetic calculations, constant multiplication and division, power calculation, add-on/discount calculation, repeat addition and subtraction, square root calculation, reciprocal calculation, grand total calculation, item count calculation, markup calculation, balance calculation, average calculation (only CS-2850), memory calculation (only CS-2850), etc. Components: LSI, etc. PRINTING SECTION Printer: Mechanical printer Printing speed: Approx. 4.5 lines/sec.
