There was nothing there but the cat food he had       >>>>>>> cooked on       >>>>>>> the day he first saw the magic mountain. He got on the computer to       >>>>>>> order       >>>>>>> something zesty from HelloFresh.

It had a simple question that he had to give it the correct       >>>>>>> answer, otherwise food nommo.       >>>>>>>       >>>>>>> The question went like this:       >>>>>>>       >>>>>>> "In math, is there a difference between the two numbers       >>>>>>> 0.999999...       >>>>>>> and 1 ?"       >>>>>>>       >>>>>>> The digits of "9" continued forever to the right of the radix       >>>>>>> point. So       >>>>>>> of course, Physfit clicked on the "yes" button.

(first of the fix number of curses Jesus had       >>>>>>> allowed him for that day). So he took a pen and paper and started       >>>>>>> jotting down:       >>>>>>>       >>>>>>> x = 0.99999....       >>>>>>>       >>>>>>> Therefore:       >>>>>>>       >>>>>>> 10x = 9.99999....       >>>>>>>       >>>>>>> Now he subtracted the former from the latter:       >>>>>>>       >>>>>>> 10x - x = 9.99999... - 0.99999...       >>>>>>>       >>>>>>> Which simplifies to:       >>>>>>>       >>>>>>> 9x = 9       >>>>>>>       >>>>>>> And therefore:       >>>>>>>       >>>>>>> x = 1       >>>>>>>       >>>>>>> "What the fuck??", said Physfit (his 2nd curse of the day).       >>>>>>>       >>>>>>> Why x which was 0.99999... and not 1, turned out to be 1? ...
