Question about Casio FX-9750GPlus Calculator

Re: help please

Mathematical notation should be adhered to in order eliminate ambiguities and avoid wrong answers.

To find you 'result' I had to try different scenarii.

The one that worked is the following

- e^(-0.019) is 0.9811793622
- raise this result to the 12th power: the result is 0.7961242598
- Multiply this last result by 250000 to find 199031.065

This is how you should have presented the question.

Calculate 250000*(e(-0.019))^12

Notice the two set of parentheses.

To type that on your calculator

250000[*] [ ( ] [ ( ] [ Shift ] [ e] [(-)] 0.019 [ )] [ ) ] [ ^] 12

In the foregoing key sequence,

- every symbol between square brackets [ ] is a keypad key.
- Numbers are not put in brackets.
- [(-)] is the change sign symbol and
- [^] is the general power key under [VARS] and above [LN]

At least it did not take me 400 years as in the case of Fermat's theorem.

Without knowing exactly what you're doing I can't be sure, but I suspect you're entering the 10^9 as something like 1 0 EE 9 .

1 0 EE 9 gives you 10 * 10^9, which is 10^10. You should be doing this as 1 5 0 0 / 1 EE 9 = .

Start with the more complicated part. Use parentheses to make sure the correct argument is entered.

1-1.00625^(-360)= the result is stored in ANS memory

Then use 2nd Ans [x:times] 1096.875 = 1227.121463

For the minus sign in front of 360, use the change sign (negate) key marked (-) or (+/-)

Without knowing the specific type of scientific notation you are trying to enter, there is no way to give you accurate information. Here is where you can download the manual from...

if you provide additional information, perhaps I can provide a more detailed answer.

Good luck.

Yes. If the calculator is showing something like ln(2) for an answer, press diamond ENTER to convert to a numeric answer. To have all results come out numerically, press MODE F2, use down-arrow to move to Exact/Approx, right-arrow, and select APPROXIMATE. Press ENTER twice to save the change.

Press the keys:

. 5 8 * 1 2 . 0 1 x^-1 * 6 . 0 2 2 2ND [EE] 2 3 ENTER

and you should get 2.9E22. Do you get something different?

* is the multiply key on the right, between divide and subtract.

x^-1 is on the left, below MATH.

EE is the 2ND function of the , key, just above the 7.

Another way to calculate this is:

. 5 8 / 1 2 . 0 1 * 6 . 0 2 2 2ND [EE] 2 3 ENTER

This should give you the same result.

. 5 8 * 1 2 . 0 1 x^-1 * 6 . 0 2 2 2ND [EE] 2 3 ENTER

Hi,

Press [SHIFT][MODE][5:Fix] and enter a number between 1 to 9. If you enter 2, your results will have 2 decimal digits.

Hope it helps.

Enter your number then press (shift) then (X10x) key. That will enter pi. then press (=) for the answer.

To figure out the percent, you simply divide your number by 100. Or, multiply your number by .xx (xx being whatever percent you want to find).

For example, if I want to know what 20% of 50 is, I would enter this:

.20 x 50 =

The answer is 10. So, 10 is 20% of 50.

As for the divide button, look for a "/".

If this helps, please take the time to give this response a positive rating. Thanks!

try hitting the diamond button and then hitting answer after it shows up, it should give you a different outcome than the original. hope that helped.

A fraction is just division of the numerator by the denominator. So all you have to do is enter the division symbol in place of the fraction bar. If you are trying to enter a mixed fraction: for example 3 3/5 enter: (3+3/5) were the / is the division button or your calculator.
