Math practice(AD) 1.4.7.53

This application was originally for my daughter. When she entered the first grade, did not like math. Often a finger count addition and subtraction within 10. I have boughten a lot of exercise book for her, but costly and spend time to check right or wrong. So I made this app for her.

Functions:
(1)Addition and subtraction within 10 for children.
(2)Lower primary use two-digit add, subtract, multiply, and divide practice.
(3)Support four arithmetic operations
(4)There is the feature of Learning clock.
