Makes Math Fun.

This app makes doing math really fun. I like how you can change how many numbers will be in the problem.

Nice!

I like trying out different ways to show my kids how to do math. One of my favorite things about this app is that nothing really bad happens if you tap on the wrong number. It just waits for you to try again -- doesn't add to math anxiety!
