One thing worth noticing here is that order of multiplication matters: it's not, as mathematicians would say, commutative.

这里值得注意的一件事法的顺序很重要：正如数学家所说，它不可交的。

First, what is the real measure of this exchangeable value; or wherein consists the real price of all commodities.

首先，这个可交价值的真正衡量标准什么？或包括所有商品的实际价格。

Addition is always commutative, whether you're adding positive or negative numbers If you swap them around, you get the same answer.

加法可交的，无论你添加正数还负数如果你交它们，你会得到相同的答案。

Wages, profit, and rent, are the three original sources of all revenue, as well as of all exchangeable value. All other revenue is ultimately derived from some one or other of these.

工资、利润和地租所有收入以及所有可交价值的三个原始来源。所有其他收入最终都来自其中的一些收入。
