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

  1. e^(-0.019) is 0.9811793622
  2. raise this result to the 12th power: the result is 0.7961242598
  3. Multiply this last result by 250000 to find 199031.065
The last result suggests that you made a mistake copying the final result.
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,
  1. every symbol between square brackets [ ] is a keypad key.
  2. Numbers are not put in brackets.
  3. [(-)] is the change sign symbol and
  4. [^] 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.

I dont understand why I keep getting the wrong exponet in trying to figure out 1500nm divided by 10^9. the answer I get is 1.5 *10^-7 -but the answer is 1.5*10^-6. What am I doing wrong?

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 = .

How is this the answer?

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 (+/-)

Hi, I just bought a calculator model# EL-501W ( by SHARP) and i can't figure out how to plug in #'s in scientific notation? Can you please give me instructions on how to do that??

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.

Hi i am trying to figure decimal for natural logarithm can i do thi with a ti 89??

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.

My problem involves converting in chemistry and im just trying to figure out how to do a problem 0.58 x 6.022 x 10 raised to the 23/ 1. I know how to calculate the problem just cant read the answer a more...

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.

How do you figure out percent on the TI-84Plus Program. Calculatr

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!

How to do fractions.

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.
