Thread: If the difference of two variables is finite.....

If the difference of two variables is finite, can you assume that each of the variables themselves are finite??

for instance, if x - y < infinity, can you assume that both x and y are finite?

thanks for the help!

You've an undefined form , what you can say is:
where
where

If two variables are finite then their difference is finite.

If their difference is defined then both must be defined.
