    Answer:

    If 0 is included in the natural numbers: 0,1,2,3

    If 0 is not included in the natural numbers: 1,2,3

    Step-by-step explanation:

    Let n denote the natural number.

    Its opposite is -n

    The sum of its opposite and 8 is

    -n+8

    This is greater than the natural number

    n<-n+8

    Solve for n

    2n<8

    n<4
