Author/Opus: This is the 273rd puzzle from Thomas Snyder, aka Dr. Sudoku.
Rules: Place each digit from 1 through 9 into the white boxes (a different digit per box) so that the indicated equations or relations are correct when evaluating from left to right or top to bottom (ignore the usual order of operations).
Answer String: Enter the nine digits in the boxes from left to right, starting with the top row, then the middle row, and then the bottom row, as a single string (e.g., “273854169”).
Time Standards (highlight to view): Grandmaster = 1:30, Master = 3:30, Expert = 7:00 (*Estimates from competition scoring, not our usual process)
