**Bosnian**, Saturday, July 7, 2012 at 6:47amIf 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
