    Sorry, like for example:

    (12x^2y^2z^3+2+24x^2)-(-2x^2y^2z^3+24x^3+24x^2)

    You need to expand the brackets and then group like terms.

    (12x^2y^2z^3+2+24x^2)-(-2x^2y^2z^3+24x^3+24x^2)

    12x^2y^2z^3+2+24x^2+2x^2y^2z^3-24x^3-24x^2

    14x^2y^2z^3+2-24x^3

    In decending order of x

    -24x^3+14x^2y^2z^3+2
