CALCULATION EXAMPLES

Basic Arithmetic Calculations

123+456=579                      123+456=                    579.
875-119=756                      875-119=                    756.
92x43=3956                         92x43=                   3956.
927/17=54.529411                  927/17=               54.529411
(741-258)x0.5=241.5          741-258x0.5=                   241.5
123-456=-333                     123-456=             -MINUS 333.

Constant Calculations

When adding, subtracting, or dividing, the operation and the last number
you enter before hitting = remain constant.

Calculation                     You Press                 You See

273+572=845                      273+572=                    845.
768+572=1340                         768=                   1340.

597-184=413                      597-184=                    413.
323-184=139                          323=                    139.

2828/14=202                      2828/14=                    202.
5460/14=390                         5460=                    390.

When multiplying, the operation and the first number you enter remain
constant.

Calculation                     You Press                 You See

295x16=4720                       295x16=                    4720.
295x27=7965                           27=                    7965.

SETTING THE TAX AND TIP RATE

Before you can calculate a tax or tip, you must set their rates.

1.  Press CAL to enter the calculator mode.

2.  Press TAX or TIPS.  The calculator displays the current rate.

3.  Press SET.  The rate flashes on the display.

4.  Enter a tax or tip rate (to the nearest tenth of a percent) as a 3
    digit number.  For example, enter 030 for 3% or 850 for 85%.  The
    display continues to flash.

5.  Press SET to store the tax/tip rate into memory.  The display stops
    flashing.

NOTE:  To view the stored tax or tip rate at any time, enter the calculator
       mode then press TAX or TIPS.  To return to the normal calculator
       display, press CAL.

Example:  Calculate an 8.5% tax rate on 1,000.

NOTE:  First set the tax rate to 8.5%.

ERRORS

ERROR appears when:

    You attempt to divide a number by 0; or

    The calculation result exceeds eight digits to the left of the decimal
    point.  This is an overflow error.

Press C/CE to clear an error and continue the calculation. Otherwise, press
C/CE twice or CAL to start with a new calculation.

Estimating Calculation Results

You can estimate the result of an overflow error (to eight significant
digits) by using this procedure.

1.  Count the number of digits displayed to the left of the decimal point.

2.  Remove the decimal point.

3.  Add to the right of the number enough zeros to make the number have 8
    digits, then add as many zeros as there were digits to the left of the
    decimal point.

For example, if the display shows ERROR 1.0142064, the answer is about
101,420,640.  If the display shows ERROR 319.70347, the answer is about
31,970,347,000.
