The SI unit for stress is N/m^2 (Newtons per square metre not Newtons per square millimetre) The figure above should be 23 .7389 * 10^ -9 or 0.0000000237389 N/m^2

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.

Press SHIFT MODE 6 then select the desired number of digits after the decimal point. Alternatively, press SHIFT MODE 7 then select the desired number of significant digits.

You need to select the number of decimal places you would like, or if you would like the calculator to behave as normal. Press SET UP and select FSE (press 1) . You now have 5 options.

0: FIX means you can choose a fixed number of decimal places for every calculation.

1: SCI means scientific notation and choose the number of significant values you would like to deal with.

2: ENG means engineering and the power goes up in multiples of 3.

3: NORM1 and 4: NORM2 are the usual or normal settings on the calculator. Most school calculations will use NORM1 mode.

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.

2.4507E-4 is scientific notation for 2.4507 times ten to the minus 4, or .00024507.

Take the 2.4507 and move the decimal point, to the left if the exponent is negative, to the right if it is positive, the specified number of positions.

If the magnitude of the result is too small or too large, the calculator will automatically switch to scientific notation. Imagine a number that has more than 12 digits to the left of the decimal point. How is that going to fit onto the display? Or a number that is 0 followed by the decimal point followed by 12 0s and then some significant digits?

This has nothing to do with the SCI display mode. Your calculator can only display a certain number of digits. The screen is limited. The maximum number of decimals you can display is 9.

By going into SETUP 1:FSE you can choose the display type FIX, SCI, ENG, NORM1, NORM2, then set the number of decimal digits.

**Be it as it may, if a number is too large or too small it will be displayed in SCIentific format.**

Note: Not all digits are important, only the first ones are. That is why in science one introduces the notion of significant digits. It depends on the precision of all the numbers involved in the calculation. NO RESULT can be more precise than the least precise number involved in its calculation.

It comes in the default format. If you want results in scientific notation all you have to do is configure the calculator to do so. Press SHIFT MODE to enter SETUP. Then select the SCI option by pressing the digit key corresponding to the number to the left of the option.

You will be prompted to enter the number of decimal digits that should appear in the result. Enter the number of significant digits in your calculations.

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.

Hello

[Shift][Setup][6:Fix]4 displays result with 4 decimal places. But if number is too small you will lose significant digits and may have a null value.

In that case you use [Shift][Setup][7:Sci]4 displays results in scientific notation digit.4digitsx10^(exponent)

Hope it helps
