With e 99 , they want to say x 1099 , But it ' s an incorrect notation . e in both maths and physics is a constant and e 2 , 71828 . It ' s called exponential and it ' s the opposite of the natural logarithm ln . I guess they used it to save space . It ' s not like any of their other notations are correct either P <| sep |> Thanks , but I ' m having a pretty nice day . I hope you are too . I understand your point . First , I ' d like to draw a distinction between valuing human life and placing value on the good or service produced by a person ' s work . If we ' re trying to artificially value the output of some individuals higher , the question is , who ' s going to pay for it ? The answer is everyone else . You and I have differing opinions on how much work constitutes a full load most people I know would consider 35 hours a vacation .
