So if x and n are functions that initially take positive values (integer or not) but are then given new arguments (e.g. x is given the value of n and/or n is given the value of x as functional inputs), indeed it is possible for each of them separately to switch signs and for the sum of them to switch signs too. Depends on the functions.
Wuuuut?
ReplyDeletex+n < x
n < 0
but n > 0
What am I missing?
Obviously no and the previous comment noted the simple arithmetic. OK - what National Review oped are you mocking?
ReplyDeleteDon't even need to note the contradiction. After subtracting x from both sides, one is left with n < 0. End of story.
ReplyDeleteSimple arithmetic of course but is there some Alternative Arithmetic ala someone like Kudlow the Klown?
ReplyDeleteWhat if x is value, though, and n is an increment of value?

ReplyDeletelong time since i took a math course, bs in 1972.
ReplyDeletei see a lot has changed.
