 Quote by Archosaur Can you give me an example of a finite number that I can't multiply both sides of an equation by?
No, but there is a finite real number that you can't divide both sides of an equation by :]

 Quote by Archosaur I would agree that the limit as n -> infinity of 1/n = zero But I'm having a hard time with this 1/infinity = 0 thing...
$\infty$, as it is used in the extended reals, is essentially a shorthard for that type of limit expression.
