Frequently Asked Questions
| |
Do you accept purchase orders?
Yes. Purchase orders can be mailed or faxed to us. Please see the additional purchasing information.
Can your software create PDF files?
No, but there are many free and commercial products that
can create PDF files from nearly any program. These programs install themselves as a printer. Instead of printing to a page, a document can be made into a PDF file. Find a free PDF writer on the web.
I bought your software awhile ago and need to install it again, but I don't have the CD. How can I get it?
You can use your product serial number to download the software from here. If you don't have your product serial number or were never given one, you can look it up here.
What are the system requirements?
The complete list of system requirements can be found here.
What is the cost of a district license?
Districts can purchase a site license copy of each product they want to buy, for each school that they want to equip. This way, each school only gets the software that they will use. For example:
| Middle School #1: Infinite Pre-Algebra & Algebra 1 |
= |
$528 |
| Middle School #2: Infinite Pre-Algebra & Algebra 1 |
= |
$528 |
| High School #1: Infinite Pre-Algebra, Algebra 1, Geometry |
= |
$767 |
| High School #2: Infinite Pre-Algebra, Algebra 1, Geometry, Algebra 2 |
= |
$996 |
| TOTAL |
= |
$2,819 |
I've been eagerly watching you, waiting for you to create a program for what I teach. What's next?
Out next program will be Infinite Calculus. We currently expect it to be ready in Fall 2012.
What is the difference between getting the download and getting a CD?
Receiving the software by download is immediate but does not come with a backup copy--that you need to make yourself. A CD, on the other hand, offers the security of a tangible disk that is harder to misplace or destroy than an electronic file, but it does not arrive immediately. When you buy and download the software, you always get the latest version. A CD may contain a slightly older version. After installing a CD version you can update your software to the latest version.
Does your software run on a Mac?
Unfortunately, our products are only Windows compatible at this time. We hope to support Mac in the future, but we are not yet working on this.
What do you mean a single-user license is good for one person on two computers?
A single-user license allows one person to use the software. That one person can install and activate the software on up to two computers at once. They are always free to change which computers the software is installed and activated on by first deactivating it from a computer on which it is currently activated (click Help > Deactivate).
Can the software be installed on a flash drive?
Yes, but it will still need to be activated on each computer on which it runs. Also, a single-user license version will still be limited to two activations at any one time.
What do you mean it can create an unlimited number of questions?
Our software generates the questions based on the options you have selected. It does not choose from a list of prewritten questions -- that would probably be slower, take up a lot more memory, and not result in nearly as many possible questions. Our software randomly chooses the variables and numbers in the question so that the question conforms to the options you picked.
Here's a simple example: You have selected one-step equations with numbers up to 10. For the first problem, the program would begin by picking the answer (21 possibilities: -10 to +10), the operation (4 possibilities: +, –, ×, ÷), and the other number in the operation (21 possibilities: -10 to +10). The program would then calculate the value on the other side of the equal sign and write the problem, formatting it nicely:
For this setup, there are 1764 theoretically possible questions. It's not infinite, but it's a lot. In reality, the number of questions it would make would be slightly lower because the program would weed out bad questions such as
"0x = 10" or "x ÷ 1 = 4." Also, for this type of question, there are other options such as one for excluding problems like "x – (–4) = 10" so it may also exclude these.
You can see that our software can't create an infinite number of questions in the strict sense (that's impossible), but it can create all theoretically possible questions for the given options (minus the bad questions). In most cases, that's a huge number of questions; a number that means you don't have to worry about running out of questions or stumbling over the same ones.
