Every answer in this clue is in number form, with no letters at all! For the meta answer, it is the total of every number of the puzzle (including 7A). Just take the number from 7A, and add the 2 digits it is made from. Hint: The result was unintentional, but it is a well known funny number
please leave a comment if you finish the puzzle :)
Fun, thanks! Initially I read "every other" as meaning every second number, which had the interesting consequence that one of the digits in the sum would also be part of the sum.
