Exponents:how to use my calculator

If by power, you mean exponents, there are several rules.

Multiplication with the same base - add the exponents
Division with the same base - subtract the exponents
Exponent to an exponent - multiply the exponents
Negative exponent - 1 over the same number to the positive exponent
Zero exponent - anything to the exponent 0 is 1

Good luck,

Try this if you have parenthesis.
(5*10^-9)*(4,4*10-9).

I'm assuming you are using a comma as the decimal deliminator and are located in Europe. (4,4 instead of the English 4.4).

Your working example also has no spaces between the elements of yoyr formula. Watch this.

In the default NORM1 display mode, values whose magnitude are less than 0.01 are automatically displayed in scientific notation.

Press SHIFT MODE 8 2 to select the NORM2 display mode. In this mode, the calculator does not switch to scientific notation until the magnitude drops below 0.000000001 .

This is all described in the "Calculation Modes and Calculator Setup" section of the manual, beginning on page E-7.

Type 4.695 [EXP] 23. It does not show the "10" in the display, but the two smaller digits to the right shall be read as exponents to base 10.

There's nothing wrong, the calculator just has the newest version of the operating system. To tell the calculator you're finished entering the exponent, simply press the right-arrow. If you don't want the new MathPrint mode, press MODE, press up-arrow to get to the second page, keep pressing up-arrow to get to the top line, highlight CLASSIC, press ENTER, then press 2ND [QUIT]. Now the calculator will display as the older operating system did.

The new MathPrint mode shows exponents, roots, fractions, and other things more like they appear in textbooks.

Press the right-arrow key to tell the calculator you're done with the exponent. Otherwise the calculator thinks you're typing in a very complicated exponent.

Uh yes it will allow you to enter a negative exponent.... press the numbers you want then hit EXP button, then hit the +/- button and then the exponent. 60 % of the time, it works...... everytime.

The calculator has several decimal display formats: FIX, SCI, NORM and ENG.
Here are examples of calculations with different formats and how to set them.

It may be a good idea for a user to get accustomed to the scientific display format, because it is the one most calculators adopt when the result to be displayed is too large or too small--when there are not enough places on the screen to display the result.

To help you with the power of 10 notation

1 billion =1000 000 000 =1 E 09 (9 zeros after 1 >> exponent 9)
1 million=1 000 000 = 1 E 06 (6 zeros after 1 >> exponent 6
1 thousand= 1000 =1 E03 (3 zeros after 1 >> exponent 3)
One= 1 = 1 E0
One tenth = 1/10 =0.1: the 1 is ONE position after the decimal mark>> exponent -01
One hundredth =1/100 =0.01 the 1 occupies the 2ND position to the right of the decimal point, exponent -02
etc.
1/1000 =0.001 = 1E-03
1/10000=0.0001=1E-04 (1 in 4th position to the right of decimal mark)
1/1000000=0.000001 = 1E-06 (1 in 6th position to the right of decimal mark)

1E-09 =0.000000001 : the 1 is in the 9th position to the right of decimal mark.

Hello,
The calculator applies the rules during the internal calculations. But all it shows you is the (final) result. It does not keep track of what exponents you used to get to the result. It is not capable of doing symbolic manipulations.
Hope you are not too disappointed.

You must put all negative numbers in Parenthesis otherwise your calculator is not squaring the negative .
