HELP! I have a test in the morning and my calculator is messed up!!

It is not calculating correctly on some things and on others it is.

EX:

Correctly calculating:

-300 PMT

30*12 N

7 I

FV

but will not calculate:

30 N

10 I

-250 PMT

FV

it is all whacked out!

SOURCE: My BAII isnt calculating correctly

Change the payments-per-year to 1 to get the correct answer. Press 2nd [P/Y] 1 ENTER.

To pay off a loan of $3245 at 12% annual interest, you can either make 6 monthly payments of $559.91 and pay it off in half a year or make 6 annual payments of $789.27 and pay it off in six years.

SOURCE: Calculating PV where n=5; i=6%; $18,400=pmt; 0=FV.

Check to make sure you have the proper value set for payments-per-year.

Please refer to the link to formula involving loan calculation: http://www.docstoc.com/docs/64563308/Calculating-Loan-Payments-Using-Reducing-Balance-Formula

This is happening because your calculator is converting the 10% interest figure into a monthly amount (ie 0.833333%), but it isn't changing the number of periods or the periodic payment into monthly equivalents. In both cases, it is assuming that payments are made at the end of each period.

So the figure of 10,168.06 is arrived at as follows:

end of period 1: 2,000.00

end of period 2: 2,000 x 1.00833333 + 2,000 = 4,016.67

end of period 3: 4,016.67 x 1.00833333 + 2,000 = 6,050.14

end of period 4: 6,050.14 x 1.00833333 + 2,000 = 8,100.56

end of period 5: 8,100.56 x 1.00833333 + 2,000 = 10,168.06

whereas the figure of 12,210.20 is arrived at as follows:

end of period 1: 2,000.00

end of period 2: 2,000 x 1.1 + 2,000 = 4,200.00

end of period 3: 4,200 x 1.1 + 2,000 = 6,620.00

end of period 4: 6,620 x 1.1 + 2,000 = 9,282.00

end of period 5: 9,282 x 1.1 + 2,000 = 12,210.20

You will need to find out from your user manual how to stop this from happening, so that all the numbers remain as annual figures. It will involve setting the number of payments per year [P/YR] to 1 instead of 12.

To reset the HP model 32S II calculator, hold down the [C] key and press the [LN] key. It may be necessary to repeat these keystrokes.

I am sorry to say but the calculator does not handle Base-N calculations. It only has three calculation types :General (basic) COMPutations, Standard deviation calculation, and regressions.

Your calculator is giving you the correct answer, telling you that 0.77 to the 22nd is about 3.1827 times ten to the minus 3, or 0.0031827 . By default, the calculator will switch to scientific notation if the magnitude of the number is less than 10 to the minus 2, or 0.01. You can put the switch at 10 to the minus 9 by repeatedly pressing the MODE key until you reach the screen showing "Fix Sci Norm" on the top line. Press 3 to select Norm, then press 2 to select Norm2.

The calculator can only show ten digits. The only way it can show a number with ten or more leading zeroes is to switch to scientific notation.

It might be more efficient to make the calculator perform a self-test. Here is the procedure.

Verifying Proper Operation (Self-Tests)

If it appears that the calculator will not turn on or otherwise is not operating properly, use one of the following procedures.

1. With the calculator off, hold down the [ON] key and press [X] (the multiply key)..

2. Release the [ON] key, then release the [X] key. This initiates a complete test of the calculator’s electronic circuitry. If everything is working correctly, within about 25 seconds (during which the word RUNNING the display should show –8,8,8,8,8,8,8,8,8,8, and all of the status indicators (except the * battery power indicator) should turn on. If the display shows Error 9, goes blank, or otherwise does not show the proper result, the calculator requires service.

Tests of the calculator’s electronics are also performed if the [+] key or the [divide] key is held down when [ON] is released. These tests are included in the calculator to be used in verifying that it is operating properly during manufacturing and service.

If you had suspected that the calculator was not working properly but the proper display was obtained in step 2, it is likely that you made an error in operating the calculator. We suggest you reread the section in this handbook applicable to your calculation — including, if appropriate, appendix A.

Hi,

you should perform calculator tests to verify the good working order of the calculator.

**-8,8,8,8,8,8,8,8,8,8** and all indicators should be lit for about 15s. The calculator displays **running**.

If calculator displays**Error 9**, another result, or displays nothing it needs to be repaired.

Hope it helps.

Thank you for using FixYa.

- With calculator OFF, press and HOLD the [X] key, then press [ON]
- Release the [ON] key, then the [X] key.

If calculator displays

Hope it helps.

Using solve and factor requires correct mode and proper equation set up. Ref to manual might help.

Hello,

You have several number display formats : Normal1, Normal2, Sci, ENG

If a number is too small or too large and the calculator cannot display it with the necessary number of digits (to satisfy your of decimal digits) the calculator uses Scientific notation

7.4E-14 =7.4x10^(-14)

If you were to use the norma1 or normal2 format you will have

.0000000000000074 but your calculator displays only the first 10 places

You should learn to use and interpret results in scientific format.

Hope it helps

It is not calculating because your decimal point and the digit separator (that's the comma which automatically displays for every group of 3 digits) got messed up. To clear, turn the calculator OFF, then press and hold down the dot (that is the decimal point symbol) key while you press the ON key..
