Benjamin Franklin said：What science can there be more noble, more excellent, more useful for men, more admirably high and demonstrative than mathematics. Let your kids learn math earlier will benefit for them. Childhood is right the period to cultivate the interest and sense of math. And arithmetic is right the start point.
‘Mary's Arith’ strengthens the arithmetic ability by providing exercises. Reasonable categories and paces within a category are arranged to make kids improving their levels steadily. This app is for addition & subtraction.

The app takes care of protecting eyesight by supplying comfortable UI with reasonable size of font.
Mary is a 6 years old lovely girl. She plays with this app after she began to learn arithmetic. Now she is good at it and enjoys it. I believe your kids will also enjoy this app and become interested with math.
