Look on the back cover and find the reset button, use a pen and press it and see if it clear the problem also check the batteries they might be dead check the back cover and see what type you need take it to the watch repair dept and buy some batteries and have them remove the back cover of the calculator and replace them. put the cover back on . your calculator will work as good as new again.

Step 2. Press the cancel button. (the display will return to zero)
Step 3. Enter time using the 1 to 0 numbers.
Step 4. Press the clock button.

Seems so simple now I know how.

Npr key on ti84


There is no nPr key per se. There is a menu item. Press the MATH key. You will see 4 menus; MATH, NUM, CPX, and PRB. Use right arrow to highlight PRB (probabilities). nPr is the second item in the PRB menu.
The way to use it is as follows:
In main calculator screen Type the n (10)
Press MATH>>> PRB
2: nPr
Type in r (5)
Press ENTER

So 10P5=30240

I don't know my phone code


Hi,

Try this steps , hope it will help you:

Unlocking:

If you have Rev 1.5 (x426) or earlier and most older models
Use the *#9998*3323# Trick (look for it on the forum)
The *#1111*WHATEVER# code will NOT work

If you have Rev 1.6 (x426) or later and most newer models
You MUST use unlocking software. Codes WILL lock your phone FOREVER

Locked: Return for Servicing

There is only 1 working solution, you must flash a copy of the firmware that is not in the locked status. (Most) Unlocking programs will NOT disable this issue, and your service provider cannot give you a code

If you do not plan to use your phone with another service provider, there is no real point to unlocking your phone other than to sell it. If you don't need to unlock it, don't take the risk of disabling the phone altogether

The *#9998*3323# Method:

1. If you have changed your phone password, change your password back to the default 8 zeros (00000000).
2. Put a SIM card that is from a network other than the one your phone is locked to
3. When Incorrect SIM error comes up, type *#9998*3323#.
4. White screen will appear with an exit option. Press the right softkey.
5. From the menu that appears, select the Malloc Fail option. This will reboot the phone and the normal service screens will appear.
6. Type *0141# and then press the green call key. "Personalization" or "Personalized" will appear.
7. Turn off your phone and put the original SIM back in.
8. Turn on your phone. You will receive a prompt to enter a password.
9. Type 8 zeros (00000000)
10. Completed. You have now unlocked your phone.

Okay, so I'm trying to fix my exponents over here. I needed to find out what 0.77 is to the 22nd Power...so i put it in my calculator and get this CRAZY number: 3.18270183 x 10^03...What the hell???? How...


Your calculator is giving you the correct answer, telling you that 0.77 to the 22nd is about 3.1827 times ten to the minus 3, or 0.0031827 . By default, the calculator will switch to scientific notation if the magnitude of the number is less than 10 to the minus 2, or 0.01. You can put the switch at 10 to the minus 9 by repeatedly pressing the MODE key until you reach the screen showing "Fix Sci Norm" on the top line. Press 3 to select Norm, then press 2 to select Norm2.

The calculator can only show ten digits. The only way it can show a number with ten or more leading zeroes is to switch to scientific notation.
