Frequently Asked Questions

Q: I downloaded the files but I can't find them. Where are they?
A:
One way to find it
them is to
start the download procedure again (but don't actually download the files).
Instead just check in the dialog box where your downloaded files were put. Then press Cancel.

Q: Why won't the apps install?
A: Make sure you are doubleclicking
on the setup program called setup.exe and not one of the other files.
(In particular don't extract the contents of the .cab file. This won't set up the app.)

Q: The Algebra Coach and some of the Technology Suite apps give nonsense results such as
1.3 multiplied by 3 equals 3. Why is this happening? How can I fix it?
A: This problem occurs if you are using an old version of the Algebra Coach or the
Math for Technology Suite and you live in a region or country that uses the comma (,) as the decimal
separator for numbers (so for example ½ = 0,5). To fix the problem uninstall the old versions
and install the new ones (version 4 of the Algebra Coach and version 5 of the Math for Technology Suite).
These versions are international aware.

Q: How do I enter a system of equations in the Algebra Coach?
A:
Starting with version 4 you must separate the equations with semicolons (;). For example
3x+4y=5; 6x+7y=8
This is a change from previous versions which separated the equations with commas (,).
This change was made to allow for internationalization.

Q: The Algebra Coach app won't factor x^2 + 2x + 5. Why?
A:
This quadratic only factors over the complex numbers.
Make sure that the complex numbers option is turned on.
