So with that, I'd like to say a few words about upgrading, and share with you a glimpse from my current project, which is different from the previous one, but it shares exactly the same characteristics of self-learning, learning by doing, self-exploration and community-building, and this project deals with K-12 math education, beginning with early age math, and we do it on tablets because we believe that math, like anything else, should be taught hands on.
所以对于这个，我想说几句关于升级 与你分享下一些我的现行项目 这与前面的那个项目不一样 但他共享了一样的特性 关于自学，从动手中学习， 自我发现和社区建设。 同时该项目涉及从幼儿园到12年级的数学教育 从早期的基本数学开始 我们在平板电脑上实现了它，因为我们相信 数学，像其他东西一样，应该被用手教授
