You can write it in different manners. But there are two special ways scientific notation and engineering notation.

**Scientific Notation** (d stands for digit, any digit), D is any digit except 0

D.dddd....d*10^(exponent) . The first digit, before the decimal mark is 1,2,3,4,5,6, 7,8 or 9

You case

567346.=5.67346*10^5

**Engineering notation**

The exponent must be a multiple (positive or negative of 3)

Your case

567,346=0.567346*10^(6). The first digit can be 0.

The number of decimal digits retained depends on the number of so-called significant digits.

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.

To enter the power of 10 with exponent use the Exp key followed by the exponent. If the exponent is negative, you must use the negation key (-) not the - key (for subtraction).

When you press the Exp key you do not type in the 10.

When you press the Exp key you do not type in the 10.

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 (-).

Use the EE key (just above the 7 key) to enter an exponent. For a negative exponent, use the +- key (just to the right of the decimal point key) to enter the negative sign.

For example, to enter 1.2 x 10^-21, press 1 . 2 EE +- 2 1

To switch the display mode to scientific notation, press 2nd [SCI] (the 5 key).

Use the (-) key for negative numbers (not just exponents) instead of the - key. The - is to subtract one value from another, (-) is to input a negative value.

Type in the mantissa, then the EE key (for Enter Exponent) above the 7 key, then the exponent. If it's a negative exponent, press the (-) key to the right of the decimal point before entering the exponent.

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.

You have a key marked [x10^X] located on the bottom row of keys.

Example: To enter 6.02x10^(23)

6.02[x10^X] 23 [=]

If you have a negative exponent, use the change sign key [(-)]

Example: To enter 6.02x10^(23)

6.02[x10^X] 23 [=]

If you have a negative exponent, use the change sign key [(-)]
