You would enter 6.02 * 10^23 as 6.02 EE 23 (EE is the key right above the 7 key)

Have fun with the chemistry :P

Hi,

a 6ya expert can help you resolve that issue over the phone in a minute or two.

Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

New users get to try the service completely Free afterwhich it costs $6 per call and covers almost anything you can think of (from cars to computers, handyman, and even drones).

click here to download the app (for users in the US for now) and get all the help you need.

Goodluck!

Look for a key that is marked EE, or Exp, or x10^x. To enter a number in
scientific notation, you enter the decimal part, then press the Enter
Exponent key, followed by the exponent. If exponent is negative, you
precede it with a press of the change sign key (-).

Once a number is entered there is no special treatment: multiply it divide, or add it.

The "problem" is not how to calculate with numbers expressed in Scientific Notation but how to enter a number given to you in scientific notation. Once the number is entered you do not have to do anything special. If you have to multiply it use the (x) button. to add it use the + button, etc.

How to enter a number in scientific notation.

Type in the mantissa (example 6.022)

Press the [X10^x] at the bottom of keypad.

Enter the exponent (example 23)

with this example you will have entered Avogadro's number 6.022x10^23

Other example

1.6 [X10^x] (-) 19 enters the electron charge in Coulombs. The exponent is negative that is why you press the change sign key (-).

All you need to know is how to enter a number in scientific notation. As to the operations you do them the usual way: For example, to multiply you enter a number (in any notation) press the multiplication key then enter the second number (in any notation) and press the = sign to get the result.

The problem is that the result may not be in scientific notation format. But for that you can configure the calculator to always show results in scientific format. Here is how to force that. Press [SHIFT][MODE] to enter (SetUp). In the screen that displays enter the number for the option SCI. You will then be prompted to specify the number of decimal digits. You will enter a number between 0 and 9. If you select 0 you will not have decimals in the result, and if you enter 9 you will have 9 decimals. What is the appropriate number of decimal place to keep in the FINAL result will depend on the number of significant digits in the measuremnets.

To enter a number in scientific notation (ex: 6.25x10^(-4))

You enter the so-called mantissa 6.25

You press the key at the bottom of keypad that is marked as [X10^x]

You enter the change sign (-) followed by the exponent 4

If your calculator is in MathIO you will be able to verify that what was entered is exactly what was neant. In MathIO, you move cursor up or down using the Up or Down arrow. When you finish entering the exponent you use the right arrow to bring cursor to the main level.

Press 2nd [SCI] to switch the calculator to display all results in scientific notation. The results are the same whether you do it in scientific notation or not, it's just how the number is displayed.

For square roots, use the square root key just to the left of the divide key. For example, 4 square-root = will give you 2.

The calculator doesn't have any way to store equations, scientific or otherwise. If you mean scientific notation, use the EE key just above the 7 key to enter exponents. For example, to enter 1.23x10^6, press 1 . 2 3 EE 6. For negative exponents, make sure to use the +- key to the right of the decimal point instead of the - key.

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.

Use the EE (Enter Exponent) key just above the "7" key. For example, to enter 3.1x10^4, press 3 . 1 E 4.

For negative exponents, make sure to use the +<>- key just to the right of the decimal point instead of the - key.

For negative exponents, make sure to use the +<>- key just to the right of the decimal point instead of the - key.

This can be done by setting the calculator to the right MODE. Press MODE 9 to turn on scientific notation. For example, compute 1 / 200 = and you will see 5 with a -03 exponent in the upper right. Press MODE 9 again and it will be displayed .005

To enter numbers in scientific notation use the EXP at the bottom. To enter .005, press 5 then EXP then +/- then 3. You will see it displayed. Then you can perform calculations with this entered number.
