    The story has the same plot as used in a few other stories / novels (e.g. in Douglas Adams Hitchhiker’s Guide and Harry Keeler’s “John Jones Dollar”) : Time traveler goes back in time to start an investment which grows enormously by the time he is ready to build the machine at an astronomical cost, thus creating a self-funding time-loop. There is no particular math mentioned except for the power of compounding. The story flows very easily - there is not much fanfare involved.
