The demo version only offers solution to the first 10 problems out of more than 60 the software has, although there are no limitations on how many times you can use it or on the time you can spend using it. Its main objective is to provide a version to interested parties that they can try before buying the full version. In the "Problems" page of Linear Algebra Decoded, there are examples of solution given by the software to some problems not covered in the demo version, which can also be used to evaluate it.
For evaluation purposes, we only offer the demo version, which does not solve all the problems of the full version, but it provides an overview of how the software works and what it offers. You can also visit the "Problems" page and look through the solutions provided by Linear Algebra Decoded to some problems not covered in the demo version.
The number of computers on which Linear Algebra Decoded can be installed will depend on the license you buy, which you can set during the software purchase process.
To do the tests it is not necessary to sign up, but there are limitations in this regard. When you request to do a test without having logged into our site, you will always be offered the same questionnaire according to the test requested. Another limitation is the impossibility to keep records of all the tests you do.
If you forgot your password, use the link "Forgot your password?" on the login page of our site. From this link you can request to reset the password, and you will receive an email with the instructions.
We would be saddened to know that you want to delete your account in Nibcode, but if you want to do so, there is the option "Delete my account" on your profile page. By confirming the deletion of your account, all related records will be deleted as well, including the tests history and the serial numbers of the products licenses you bought from us.
