We showed that in noncommutative case, orthonormal base vectors can be chosen to be unitary operators of any fix order.

我们证明了，在非交换条件下，能够选择标准正交基向量成为任何固定序的酉算子。

These operators group from left to right, which accounts for the fact that we can concatenate input and output operations into a single statement

这类操作符从左向右地结合，正好说明了程序员为什么可以把多个输入或输出操作连接为单个语句

We'll see in Chapter 14 how to define overloaded versions of operators.

我们将在第十四章中学习如何重载不同的操作符版本。

But many of these subscribers spend very little, being the beneficiaries of a vicious price war among operators offering calls as cheap as one paisa ($0.0002) per second.
