Scientific notation is a number format that has the following structure (d stands for digit)
one digit decimal mark several other digits [times] 10 raised to power of exponent
d [decimal mark] dddddd...[x] 10^ (-) dd

Here are two examples the last two results. The number of digits after the decimal mark is select by the user depending on the number of significant digits in the data. The exponent can be positive or negative.

In you case, to enter x10^ you press the [EE] key (no 10 is entered) the sign of the exponent and the value of exponent.

OOPS Sorry
"Here are two examples the last two results. The number of digits after the decimal mark is select by the user depending on the number of significant digits in the data."

"Here are two examples (the last two results). The number of digits after the decimal mark is selected by the user depending on the number of significant digits in the data."

"In you case" should read "In your case"

### Scientific notation on BD - 107i calculator?

Of course it is possible!

There seem to be many ways to do this on this calculator.

Assuming we cannot do scientific notation, we can always do

6.02 x 10 ^ 23 / 3.01 x 10 ^23. However, we have to put brackets in to get BEDMAS to work correctly!

6.02 x 10^23 / (3.01 x 10^23) - for the 10^23, type 10 then the y to the x key and then 23.

Using the scientific notation, we can type in 6.02 EXP 23 / 3.01 EXP 23.

Good luck with your chemistry test tomorrow!

Take care,

Paul

### WHAT IS THE E CODE

Does the E code look like 10.8372487489E12?

If so, the calculator is either set to scientific notation mode OR the result was an answer that was too big to display on the calculator, so it converted it to scientific notation. To convert from scientific notation back to regular notation, move the decimal to the right by the number of times after the E. In this case, the number after the E is 12, so we have to move the decimal to the right 12 times. In this case, I get the final answer as 10 837 248 748 900.

Good luck.

Any questions, let me know.

### Scientific notation

All calculator use scientific notation if the result is too small or too large. Some, like the Casio FX9750G II, offer you two Normal displays, Norm1 and Norm2 that have different limits when numbers are converted to scientific notations.
Here is how to set one or the other.
In Run>Mat press SHIFT MODE (Setup). Scroll down or up to reach the display line. Press F3 to select Norm1 or Norm2.

### How do I change from having the answers displayed in scientific notation to normal number display?

You can set your display mode to FIX or NORMAL ( 1 or 2) if you have them. However if the result is too small ( less then 0.001) or too large the calculator will use the scientific format. Generally if there are not enough display positions to show your result, the calculator uses scientific notation.

### Scientific notation when not wanted.

Unfortunately, you don't. For numbers whose magnitudes differ too greatly from 1, the calculator automatically switches to scientific (or engineering) notation. You can press MODE and change the display settings, but there is no setting that will force the calculator to show this number without an exponent.

### I have a TI-30XS Calculator and cannot figure out why the thing won't work when I try to divide numbers with scientific notation. The calculator appears to be adding exponents when it should be...

One solution that you might try is to put the scientific numbers in parentheses. For instance open parenthesis, type in the first scientific notation then close parenthesis, next hit the divide key and then open parenthesis and type in the 2nd number in scientific that you are dividing by and then close parenthesis. Hit enter or =. I'm not sure if this will fix your problem, but it is worth a try.
