    Help with transfinite numbers

    Some people are telling me that you can perform arithmetical operations with transfinite numbers, but other people are telling me that you cannot. My question is this:

    Is the following true or false:

    (aleph-0) - 1 = (aleph-0)

    It is true. See cardinal subtraction in Wikipedia.
