There must be an error in what you report. You pressed MODE then 4: Base-N and now your calculator is in base-N calculation mode (the DEC, Hex, BIN, OCT) numeration keys are active.

To do statistics you must put the calculator in STATS mode.

Press MODE: You have 6 computational modes to choose from

1: COMP, the general computational mode

2:CMPLX, for calculation s with complex numbers,

3: STAT for statistics,

4: Base-N, binary, octal, decimal, and hexadecimal numeration

5: Equation, solving mode, etc..

**For statistics, choose 3:STAT**

Press the [SET UP] key, followed by the 0 key to bring up the display menu. You can select "FIX" followed by the number of digits to the right of the decimal point, or press cursor-down and select one of the NORM modes. Press [ON/C] to exit the menu.

Be aware that some numbers cannot be displayed exactly. For example, 1/3 is a 0.3 followed by an infinite number of 3s.

1*10^(-3)

Because you're using -3 as an exponent, you need to put the whole thing in the parentheses.

I'll bet you're entering 10 before hitting the EE button.

If you try to put in 6.02x10^23 as 6 . 0 2 x 1 0 EE 2 3 then the calculator sees that as 6.02 times 10 times 10 to the 23.

Put it in as 6 . 0 2 EE 2 3

The EE key means "times ten to the." There is no need for you to put in the 10 yourself.

Make sure you use the (-) key in the left column above the RCL key to enter negative exponents, not the - key which subtracts.

Do get all results in decimal instead of fraction notation, press SHIFT [SETUP] 2 to select LineIO mode.

If you mean to do x power y, so you must have an ^ button or y with little x(top right) this is the power. And when you want negative power like -2 so input 2 then "+/-" button (it's change the sign of the number).

You have to set how the calculator handles numbers. To do this follow these steps:
1. Press the 'MODE' button. This brings up the calculator's main settings page.
2. Scroll down until you reach a field titled 'Exact/Approx...'. This is the setting for how the calculator handles numbers, whether it will show the exact answer (which is usually in fraction format) or whether it will show an approximate number (which will be in decimal format).
3. Press the right arrow which will bring up the options for that setting. You must now choose between three ways of handling numbers:
-'1:AUTO' will determine which type of answer the calculator will give based on what numbers you want it to calculate (e.g. if you want an answer in decimal format just add a decimal somewhere in your problem).
-'2:EXACT' will automatically display all answers in either whole number format or in fraction format.
-'3:APPROXIMATE' will automatically display all answers in decimal format.
4. After you have selected one of those options pres enter one more time to get out of the 'MODE' dialogue and return to the 'HOME' screen. Now try a problem and see what happens.
Personally I like using 'AUTO' because then I don't have to keep returning to 'MODE' when I want either or.
Hope this helped, I had the same problem when I first started using the TI-89.
