    If your expression mean:

    5 * 5 - 35 + 21 - ( - 3 ) * ( - 3 ) * ( - 3 )

    then:


    ( - 3 ) * ( - 3 ) = 9

    ( - 3 ) * ( - 3 ) * ( - 3 ) = ( - 3 ) * 9 = - 27

    - ( - 3 ) * ( - 3 ) * ( - 3 ) = - ( - 27 ) = 27


    5 * 5 - 35 + 21 - ( - 3 ) * ( - 3 ) * ( - 3 ) = 25 - 35 + 21 + 27 = 38
