    What is the difference between R and -infinity to +infinity?

    I'm a bit confused. What is the difference between R and -infinity to +infinity.

    It sounds like the same set of numbers to me.

    Thanks

    The difference is in the symbols.
    We use the symbol \mathbb{R} to denote the set of real numbers.
    So \mathbb{R}=\(-\infty,\infty).
