The limit as x approaches infinity of x+x = the limit as x approaches infinity of 2x. The limit is unbounded. I hope that this is close enough to your original statement.

#245 that is still a limit at infinity not a number. Consider the equation form before inf. + inf. = inf. If we were to subtract by infinity than we would end up with inf. = 0 infinity is not a number
#239 infinity is more of a concept than a number, so I am not sure that you're allowed to preform arithmetic operations on it. I can however prove a similar statement, not sure if it counts though. That as two numbers become increasingly large, so does their sum.
