NumberWiz 818: A solution

The question was: how do you add, subtract, multiply and divide 3 4 7 9 25 50 to get 818 ?


I mentioned that one solution would be to get to 33 as a first step: 
33 = (4 x 9) - 3. Now multiply by 25 to get 825. Then subtract 7 and you're there:
818 = (4 x 9 - 3) x 25 - 7.
