[i]GeoGebra 计算器套件[/i]是将几何和代数关联起来的动态数学应用. [br][br]您可以访问在线 [url=https://www.geogebra.org/calculator][i]GeoGebra [i]计算器套件[/i][/i][/url]. [br][br]The [i]GeoGebra Calculator Suite[/i] will soon be available for Android phones in the Google Play Store and for iOS phones in the App Store. [br]If you are using a different phone, you may want to open [url=https://www.geogebra.org/calculator]GeoGebra Web[/url] in your phone's web browser instead.[br][br]In this tutorial, you will learn how to use the [i]GeoGebra [/i][i]Calculator Suite[/i]. We are still working on including all [i]GeoGebra Graphics [/i]tools and functionalities, which you can use in the Online App, in the Mobile Apps as well, to give you access to the full [i]GeoGebra[/i] power. You can try the examples in this tutorial also on your mobile phone, if there are small differences we will let you know.
