fully functional no problems just like new- a flashmaster is an interactive way to teach kids their times tables and test them on them. The FlashMaster is a hand-held computer to help your child master their math facts (all four operations). It goes as high as 9+9 in addition, up to 18-9 in subtraction, up to 12 x 12 in multiplication, and up to 144 divided by 12 in division. If your kid gets a problem incorrect, it gives him or her the correct answer AND repeats the same problem two more times for practice
