This app is a shooting factoring game. Put the button of a prime number, emit the ray and divide the number written in meteorites! This app specifies the factors of the number by using a factoring algorithm. Destroy all meteorites quickly not to be damaged by them. This is a calculation game that can improve your calculation and memorization skills by turning an arithmetic/math quiz into a game. Many meteorites fall simultaneously. So, you can choose which of them you divide by tapping the image of the cannon. We prepare the level of "Easy" to "Impossible". Can you complete all of them?
