### HOw to change FSE code on Sharp Advanced D.A.L. EL-531X

Hi there,

To change the FSE code on your SHARP calculator press SETUP and choose 0. FIX means that it shows you all the decimal places. SCI is scientific notation, ENG changes the scientific notation in groups of 3's. NORM1 and NORM2 are your normal number ranges, however norm2 starts from zero and anything negative will be written in scientific notation.

### How are numbers in scientific notation entered in Aurora SC150X calculator

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.

### Just got a SHARP EL-531X, it won't do simple calculations with scientific notation, It keep saying

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.

### I need to know how to divide, mutiply, add, and substract in scienctific notation on my Casio fx-300ES

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 (-).

### How would type in scientific notation?

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).

### Scientific notation

You have to use the EE button right next to the parenthesis and the sigma plus button. So 1.7 EE and then your exponenet. If it is a negative exponent you need to hit the negative button before you type in the number.
