I subtract in left-to-right order, first subtracting 1 in the leftmost column, then 2 in the next column to the right, etc. Step 1 is omitted and is identical to the photo "Subtracting 123456789 from 246913578 in left-to-right order - Step 1". This step subtracts 1 from the 1st column from the left. I simply subtract 1. CC0 waiver: To the extent possible under law, I waive all copyright and related or neighboring rights to this work.
