Binary Addition and Subtraction Problems

The applet below creates problems for you to practice adding and subtracting in binary and hexadecimal. You will be given a computation to do in one of those bases. When you have computed your answer, enter it in the box and then click on the "Check Answer" button to find out if you did the problem correctly. You may try the same type of problem with different numbers by clicking on the "Same Problem" button, or choose to practice calculating either the next type in sequence ("Next Problem" button) or a random type of problem ("Random Problem" button).

You need a Java-capable browser such as Netscape 2 for Windows or Netscape 3 for Macintosh to be able to work with the units problems.
