Question 24
Fill all nine boxes with digits 1–9, using each digit exactly once. In every arrow, add 12 to the number on the left to get the number on the right. Also find the digit in the “?” box. Read the five arrows in this order: upper-left, lower-left, upper-middle, lower-middle, right. Within an arrow read boxes from left to right. Enter all nine box digits in that order, separated by commas.
