Description:

This interactive Java applet helps the learner conceptualize the addition of signed numbers. The user clicks and drags red and black colored chips to a circle to represent a problem and then simplifies by placing a red negative chip on top of a positive black chip. The student actually sees the opposite pair disappear. Users may practice problems generated by the computer, themselves or free play with the chips. There are separate tabs to access information for the learner, the instructor and to seek help.
