Sign Up for a Username
1. On the main JS-83 page, click on 'Sign Up', located just underneath 'sign in':
Note: If someone is logged in, you will need to log them out by clicking 'logout'.
2. Next, you will need to select a unique UserName. Type in your selection. Try to be creative so as not to pick a duplicate.
3. Then you will need to select your PassWord Core. This will not be your full password. This will be the foundation of your password. For example, you might select 'calc' as your password core. Your final password will be emailed to you. Your final password will contain the password core that you input here, along with some additional random characters.
'What's with Password Core?' This is a form of email verification. You must provide a valid email address in order to receive your full password.
4. You must also provide a unique, valid email address. This means one JS-83 account per email address.
5. Finally, you must answer the Re-Captcha correctly in order to create your account.
6. Once you have done all the previous steps, click the button 'Sign Up'.
7. If you were successful, you will get a page that looks like this:
You should receive an email from 'noreply@algebrahut.com' shortly with your password.
8. You should write down the following for your records:
- UserName
- Password (once you get in in your email)
- Email Address used
- Data URL, if you would like to see/share your data
Note: I currently do not have any way for you to change or request a password. This means that if you lose or forget your password, you will have NO way to retrieve it.
Unsuccessful Sign Up
If you were NOT successful, then the sign up page simply reloads, with blank text boxes and a new Re-Captcha. There are no error messages at this time to let you know why you were not successful. Possible reasons that your registration failed:
- You selected a UserName that is already in use.
- You input an email address that has already been used.
- You did not successfully pass the Re-Captcha
Sign Up Successful, but No Email
If you were successful in signing up and got the 'sign up successful' page, but did not receive an email with your final password, then consider the following:
- Check the Junk/Spam folder of your email account.
- Are you sure you typed in your email address correctly, including the '@somedomain.com' part?
- It is possible that your email filters are blocking the email. You might want to put 'noreply@algebrahut.com' on your 'allowed list' before signing up.

Logging Into JS-83
Once you have a UserName and Password, go to http://www.algebrahut.com/js-83 and log in. Type in your User Name and Password and click 'Login':
Logging Out
If someone is already logged into JS-83, you'll need to log them out before you can log in. Click on the link that says 'Logout':
Also, after you are done using JS-83, this is how you would log yourself out.
Using Data Storage
You do NOT need a UserName/Password to use Data Storage. However, the data storage is only temporary (if you leave the web page, your data will be lost). You need a UserName/Password to SAVE stored data. Saving stored data allows you to leave the website and come back later and retrieve your saved data.
To use the Data Storage, first expand the Data section.
Next, select the type of data that you'd like to store. You can store equations, lists, or matrices. The buttons do not appear clickable, but click on a box to view the Data Storage for that data type.
Equations
To store an equation, either click 'Y1-Y5' or 'Y6-Y0' or both, depending on where you want to store your equation.
In the box below, I have clicked on 'Y1-Y5'.
You can store up to 10 equations at a time. Be sure to format your equations correctly (function format). For graphing, you can select from one of 10 different colors for your graph from the drop down menu at the right.
To use an equation that you've stored, you need only refer to its location. For example, to graph the equation stored in 'Y2', I need only type 'graph(Y2)' into the input box and hit enter:
Then you get your graph in the color you selected:
When you are done using the Equation Storage, you can collapse it back down by click on 'Y1-Y5' or 'Y6-Y0' again:
Lists
To use the List Storage, first click on 'Lists' under the data section:
Then enter your list data. You can store up to 6 lists at any time. Be sure to format the lists properly (list format).
To use a list that you've stored, you need only refer to its location. For example, to find the mean of the data set stored in 'L2', I need only type 'mean(L2)' into the input box and hit enter:
Then you get the result:
The nice thing about using storage here is that you type in the list of data once and you can use it over and over again. For example, now we could find 'median(L2)', 'midrange(L2)', 'standev(L2)', and 'P(30,L2)', all without having to type in the list again.
Matrices
To create a matrix for storage, you must click on 'MtrxA-E'. This will display the data storage for matrices A through E, but will also display the matrix creator. (It is highly recommended that you use the matrix creator to create a matrix, as opposed to typing in your matrix manually. See matrix format for more information.)
Enter in the size of the matrix you wish to create (rows X columns) and click 'Edit'. You will see an empty table of the size you indicated in the Output Window.
Fill in the table with your matrix entries.
To save your matrix to Data Storage, click on a 'Save to' button. For example, if I want to save this matrix to [A], I click on the button 'Save to [A]'.
To use this matrix from storage, you can simply type in its name ([A] for matrix A) or expand the 'Matrix' section:
From here you can view and use any matrices you've stored by clicking a button. For example, to find the determinant of this matrix, you only need to type in 'det([A])' into the input box and hit enter. You'll get this:
