From Joseph Baird:
Add the numbers before they disappear! Adding Antics is a fun way to practice mental addition skills. Three levels of play (Greenie, Whiz or Guru), each of which gradually increase in difficulty, will challenge players of all ages and skill levels. But don't worry! Special items (Number Bomb, Time Freeze, and Magnet Assist) can help out when time is running short. Once you've been pushed to your limit - it happens to us all! - you will be given a summary of how well you did (longest running streak, problems solved, and percentage answered correctly). Great for parents, teachers and students of all skill levels!
