Very helpful
I love that the app will last a long time since you can set the difficulty of the addition problem. A handy app to have for all ages...good learning tool.....great addition tool.
Awesome!
Wish I had this type of app when I was in school. Math concepts were hard for me and a practice app like this would have been great. This is perfect because it can be set for different levels and you can even customize the color scheme.
