    the difference between triple a number and double a number

    The phrase a number means an arbitrary variable, let's call it x.

    Triple a number means we multiply x by 3:
    3x

    Double a number means we multiply x by 2:
    2x

    The difference means we subtract 2x from 3x:
    3x - 2x

    Simplifying like terms, we have:
    (3 - 2)x = x
