把乘法器系数表示为CSD形式，将常系数乘法优化为最少的移位加操作。

Coefficients of the multipliers are transformed into CSD forms and the multiplications are substitute by minimum shift-add operations.

相对于浮点计算法，移位-加操作最大的优点是计算简单，特别易于超大规模集成电路实现，因而使硬件实时处理图像信号成为可能。

Compared with the floating-point computing method, the shift-add operation is simpler, and can be implemented easily by VLSI, which enables the real-time image processing to be realized by hardware.

它们是规范的数学操作：加、减、乘、除。

These are the canonical, mathematical operations add, subtract, multiply, and divide.

And so I'm going to go back to this idea of a class, and let's build the first of these, and that is shown right here on this piece of your handout.

你把半径加到一起,你不会把角度加到一起，你需要再笛卡尔坐标下，进行这个操作,那么我这里在讲的就是。

Append sticks the list on the end of the list, append flattens it, one level of course.

因此串联加操作符和append方法，是不同的，Append方法把一个数组。

So really, the rule of thumb if you think back to Scratch is -- that any time you write a statement -- -- something that does something in one line of code -- you generally need the semicolon there.

实际上，根据经验，你们回忆一下在Scratch中,任何时候你们写一条语句-,处理一些操作的一行代码-,你们通常需要在那里加个分号。
