Frequently Asked Questions

Do you accept purchase orders?
Yes. Purchase orders can be mailed or faxed to us. Please see the additional information for purchasing departments.

What is the cost of a district license?
The price is the cost of a site license times the number of schools to equip minus 10%. Essentially a district buys a site license for each school but then receives 10% off. For example, a district that equips eight schools with both Infinite Algebra 1 and Infinite Pre-Algebra would pay $499 × 8 - 10% which is $3,592.80.

Do you plan on expanding into other subjects like Geometry?
We are currently working on Infinite Algebra 2 which should be released in early 2008. Following that will be Infinite Geometry about a year later (in 2009). Following that will be products for Pre-Calculus and Calculus.

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 disc that is harder to misplace or destroy than an electronic file but does not arrive immediately. Currently the download version of Infinite Pre-Algebra includes an update that the CD version does not include (details on update). This update can easily be downloaded and installed from within the software. The download and CD versions of Infinite Algebra 1 are identical.

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 it can create an unlimited amount 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. It 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. 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 then calculates the value on the other side of the equal sign and writes 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 it would make would be slightly lower because it 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 it can't create an infinite amount 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 amount of questions; an amount that means you don't have to worry about running out or stumbling over that same ones.
