From Cambridge to Eternity: “It’s the Percentage Change”
If any of us gives us any number, we can prove that the number might represent the US GDP of a certain year in an imaginary currency unit, say, bancor . Suppose that the number given happen to be 123,456,789,000 and the US GDP of 2023 be 27.4 trillion dollars .
