Синие карты - для сложения, а розовые - для вычитания. Улучшить математику!
Brush up on your math skills with Quick Mathematics! The blue cards are for addition, and the pink are for subtraction. If a blue and pink are next to each other subtract the pink from the blue. If two blue cards are next to each other add them. Do it quick though, or the game will be over! The quicker you are the more you can answer and the better your score will be. There's no timer, so you can focus 100% on the math and not the time.
This is a great game to train your math skills with. Practice makes perfect!
