This tutorial explains base 2 or binary numbers and shows you how to convert base 10 numbers to binary.
The tutorial is made of information pages and question pages. After a few pages of information, you must answer a question before you can continue.
Questions in the tutorial are multiple choice. Questions are shown in the top frame of the window, and four possible answers are listed under the question.
Click on the correct answer from the list, and you will see feedback for your choice in the bottom frame.
If your answer is correct, you will go on to the next page. If your answer is not correct, you will be asked to try the question again.
