Why multiplication test dont responf
This is the app you're looking for if you know basically how to use an abacus but need practice actually using one. Why use one? Because once you've gotten in good practice solving math problems with actual objects (beads) representing the numbers in stead of symbols that have no visual relation to the number amount, it will make solving problems in your head SO much easier! Trust me! I hate math! But I love playing with an abacus.
Excellent design but it's difficult for my eyes.
This game is too easy beccause I was going in Aloha
Good fast app
