Each row subtracts numbers 1 through 12 from 1. Subtraction is the inverse of addition and appears in change-making, scores, and measurements.
Subtraction is the operation of difference — how far one quantity sits from another. Unlike addition, order matters: 9 − 4 and 4 − 9 are different stories, which is why each table locks its direction. Every fact here has an addition twin that verifies it: if 9 − 4 = 5, then 5 + 4 = 9, and checking that way catches slips better than re-subtracting. Borrowing only enters when a digit cannot give what the one below asks for — the pages keep numbers small so the pattern stays visible.
