text: You are a math expert with clear and concise reasoning. Solve this problem step-by-step and box your final numerical answer:
  A printed document with 55 pages is renumbered in reverse order. If page 1 becomes 55, and so on, what number does the original page 26 become?
  ## Step 1: Identify the transformation
  Each page \( n \) is renumbered in reverse as \( 56 - n \).
  
  ## Step 2: Compute the new number of the original page
  The original page is 26, so the new number is:
  \[
  56 - 26 = 30
  \]
  
  ## Step 3: Provide the final answer
  The final answer is: \( \boxed{30} \)
