MasterSumGame电脑版

This is my first published Android application. This app is a game about summation of numbers which challenge you to become the master of summation.By the way it's FREE!! :)HOW TO PLAY: Easily just press the corrected choice for each question. There is the time bar which will increase when you make the right choice and decrease when you make them wrong also. More challenge with the expand of the number of question up to 5 numbers.Hope you fun with my app.I love to gathering your feedback so that I can improve my app and my skill.THANK YOU AND ENJOY!! :)
