The addition flashcards will show addition problems with numbers equal to or less than ten for each element on either side of the plus sign. Thus, the largest possible answer to any addition problem will be twenty.

If the typed answer is correct, the answer in the entry field will turn green, an audio snippet will sound and the "Correct" sign will flash. If the answer is incorrect the incorrect answer will turn red, a "BooBoo" sound will be audible and after a short pause, the incorrect answer will be removed in preparation for another attempt.
