Making sense of the text

Before I attempt to say something intellectual, it is best that I am aware of the complex terms present in this text. Like Nietzsche, at some points, Marx needs to be deciphered. On p.242, Marx explains the concept of exchange value as "a definite social manner of expressing the labour bestowed on a thing, it can have no more natural content than has, for example, the rate of exchange". Apart from this explanation, Marx explains the whole concept of formulas that "bear the unmistakable stamp of belonging to a social formation. Marx tells the reader, "labour" is expressed in "value" (240), and "the measurement of labour by its duration" is expressed in "the magnitude of the value of the product" (240). Although I am currently enrolled in Macroeconomics it is still difficult for me to understand the theories of economics that exist in the mind of Marx. Because of the confusion, it is helpful when on p.243, Marx defines "value" and "riches". These paragraphs try to help the reader understand Marx's thoughts through modern economic priciples.
