Query: Very disappointed

The little handheld game did not live up to the standards of the other Blaster products my children have been exposed to. My seven year old threw it down and said it didn't make any sense. My sixteen year old finally figured out how the game worked. It is not at all what we had imagined. The answers to the add and the substract problems are answered in increments: Example 100 - 75 = the highest choice you are given may be 12, you choose that and then keep choosing until your final answer adds up to 25! I have never seen a math learning toy that was so confusing! It works properly, but not a good product for the age group it was advertized!
