The downloaded manual pages 3 and 4 states, click the "setup 03" key and it will change to normal mode.
10000/8.1=1234.5678901 (normal mode)
setup 00 setup13 1234.568 (fix mode tab=3)
setup 01 sci mode
setup 02 eng mode
setup 03 normal mode
or just click the reset switch behind the ( Sharp el531w ) calculator, data will be deleted.

Hi,

best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

Hi eamon at hom,

Doing fraction on the Sharp El 531W really isn't that bad. I had to use pictures because, the symbols will not transfer over to your posting for me to show you. When you select the [ON/C] this clears the calculator of previous calculations and, data so that they won't interfere with your new calculations.

Let take the first example where a mix number is being added to a improper fraction. Because I used the [a^b/c] key this makes the calculator display the answer in a mixed fraction format or, a proper fraction format. If I press the [a^b/c] key again after the answer the format will change to a decimal format. The fractional formats are displayed in a mixed number, improper or, proper fraction formats. A improper fraction is really a proper fraction number with the top number (numerator) is greater than or equal to the bottom number (denominator).

[ON/C] [3] [a^b/c] [1] [ [a^b/c] [2] [+] [4] [a^b/c] [3] [=] mixed number results. Now let's do the same calculation as a improper or, proper fraction format.
[ON/C] [7] [a^b/c] [2] [+] [2] [a^b/c] [3] [=] still a mixed number result. Even though I enter the fractions in a improper and, proper fraction formats the calculator will still display in a mixed number format. This is because the calculator first displays as a mixed number if it can. If it can't then it will display the value as a proper fraction and, never as a improper fraction. To convert from a mixed number to a improper fraction format if the calculator did not convert it to a proper fraction, I have to use [2ndF] [d/c] keys on the command line.

This show a little more complex raised power use of the [a^b/c] key.

This shows the [2ndf] [x^-1] keys being used to calculate fractions.

When I first saw this question being asked it, was answered with just use the / command. Which that isn't really a good answer because, in math we like to use elimination. If you use the / command eventually the numbers are going to be rounded off and, your not going to be able to eliminate anything. If you have any further question on how to preform fractions with this calculator be sure to post your comment and, I'll be glad to help.

Hello,
1. To restore the default setting you have to reset the calculator:
- With the calculator switched ON press the [2nd][+] [ENTER] Move the cursor down to Reset or press the [7] key.
-Choose to reset [RAM] ( 1: all ram; 2: defaults) or [ALL] (1: all memory. Whatever choice you make needs to be confirmed in a subsequent screen.

To reinstall the applications you need a TI silver cable, and the TI Connect software. Install the software before connecting the calculator to the computer.

When you are done, connect your calculator to the computer, execute the TIConnect software . You can then drag and drop on the TIconnect window the app you want to restore.

Hope it helps.

Hi there,

Press SETUP and choose 0 for FSE. Then choose 3 for Norm 1. This will put the calculator back to the original setting.

Well, before trying something like opening the calculator, I'd advise archiving anything that you want to save to your PC. But what's done is done.
Are you sure that you're inserting the batteries with the proper polarity? Are you sure that the batteries are good?
It does sound to me like some sort of hardware problem, but strange things could happen if RAM gets corrupted (such as by being without power for too long).
It could be that the calculator really is on, but isn't displaying anything. The following solutions assume that the calculator is on.
Try a warmstart, that is hold down the ON key, press and release C, release ON.
If that doesn't work, try forcing a warmstart with a paper-clip reset. Remove the upper right (as viewed from the back) rubber foot. You'll see a small hole with the letter R next to it. Insert a straightened paper-clip (or something similar) straight in as far as it will go, and release it.
If that doesn't work, and you're willing to lose everything you had stored on the calculator, try clearing all user memory. Hold down ON, hold down A, press and release F, release A, release ON.

Nothing happens when I press a number??

Hello,
There is no lock button. Calculator may be configured to be in computational mode you are not familiar with: It may be set to do base calculation on base 5, hence the p (pental). Press the reset button on the back, and the default configuraion will be restored.
You should give some time to learn the different mode of calculations.
Hope it helps.
