Scrabble word spans through a double-letter square and a double-word square?

Would you double the whole word first, then add the remaining of the double letter? Or would you double the letter first and then double the word? For example: if I have the word DODGE with the 1st D in the double-letter square, would it be like [D(2) + O(1) + D(2) + G(2) + E(1)]x2 + D(2) or would it be like [D(2) x2 + O(1) + D(2) + G(2) + E(1)] x2 ?
