Circle 0

This interactive Java applet game has a user adding positive and negative integers to arrive at a sum of zero. Seven overlapping circles form a ring similar to a Venn diagram. Five blue numbers are in position when the game begins. The remaining nine numbers (from -6 through 7) must be placed in the empty spaces to produce a sum of zero in each circle. There is a unique solution for each puzzle. Instructions for users and teacher information are available through links at the top of the page.
