Mathematics

Train your brain with mathematic operations.

The principle is very simple: on the one hand the app proposes a target number, and on the other hand it gives you some operation symbols together with a collection of digits. Then you have to reconstruct the operation to get the number.

This exercise is excellent for training in mental computation. Doing it is a very good practice for mathematics, for all the arithmetic operations: addition, multiplication, division and subtraction.

There are several levels. The first ones are very easy, ideal if you are learning to count. And step by step, it introduces more and more difficulties, becoming an excellent brain training.

与数学运算训练你的大脑。

其原理很简单：一方面是应用程序提出了一个目标数字，而在另一方面，它给你一些运算符号加上一个数字集合。然后，你必须重建操作以获取数。

这个练习是非常适合在心算训练。这样做是对数学的一个很好的做法，对所有的算术运算：加法，乘法，除法和减法。

有几个层次。首当其冲是很容易的，理想的，如果你正在学习计数。一步一步，它引入了越来越多的困难，成为一个优秀的大脑训练。
