Re: exponents

You will have to use the X^y function, which is on top of the fourth key from the right of the rows containing the big buttons (on top of the multiply symbol).

Now let us say you arte interested in 2^ 5 = 32, you type two and then the shift key and then the X^y key, followed by the number 5 and enter. You should see 32 on the screen

Try this if you have parenthesis.

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.

How do i get rid of the exponent?

Do not panic!. Press [MODE]. On first line of MODE set up screen use arrow keys to highlight NORMAL and press [ENTER].
Use down arrow key to go to the line starting with FLOAT, and highlight the number of digits you want your results to display (from 0 to 9). Keep in mind that with 0, all your results will be rounded to the nearest integer. With 9, you have a large stream of digits (not necessarily a more accurate result).

However, if your results are too small or too large, the scientific display format ( with E )will be used regardless of the MODE setup.

To solve 10 raised -3, to be done with cal., answer in the display ought to be .001

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
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.
