    Chapter Summary
    ::章次摘要

    This chapter  has  revisited  the fundamental  concepts from algebra that are necessary to build and manipulate the mathematics to be learned  in precalculus. The rules  of numbers and number systems, as well as the properties of operations, are essential to the material ahead, including working with triangles and functions. With the ideas and steps of algebra under your belt, you're ready for the next level. You might find that lessons that once made you ask yourself, "When am I going to need this?" are now super-helpful in solving applications of real-life mathematics!
    ::本章重新审视了从代数中产生的基本概念,这些概念对于构建和操控预估中学习的数学是必要的。数字和数字系统的规则,以及操作的特性,对于未来的材料至关重要,其中包括三角和函数。随着代数的想法和步骤在你的腰带下,你为下一个层次做好准备。你可能会发现,当你问自己,“我什么时候需要这个”时,你就会发现,这些教训现在对解决实际数学的应用非常有帮助!
