This fun math games combines Pac-Man and math, or, more specifically, factors. You need to eat the numbers that are factors of a given number, such as 18. But if you eat numbers that are not factors of 18, you lose a life! For example, with the number's 18, you can eat numbers like 1, 2, 3, 6, and 9. If you eat numbers like 4, 5,7 and 8, you lose a life. You also have a little purple enemy. Stay away from him! Hours of fabulous learning fun to be had when you play Factor Feeder!
