Swap Sums is a fun math game that will test your level of knowledge in this science. In this game you have to pass the levels and get the number zero at the end of each of them. You will see two types of cubes on the screen. Some of them will be blue and have positive numbers. Others will be red and you will see negative numbers in them. Look carefully at everything and use the mouse to start moving the cubes around the playing field. You will need to build mathematical equations from these cubes, solving which at the end you will receive the number zero. As soon as this happens, the level will be considered completed, and you will receive points for this.
