A-b>1

The inequality a − b > 1. - Solve for a: a > b + 1. - Solve for b: b < a − 1. If a and b are real numbers, the solutions are all pairs (a, b) with a > b + 1 (i.e., the region above the line a = b + 1 in the ab-plane). If a and b are integers, then a − b > 1 implies a − b ≥ 2, i.e., a ≥ b + 2. Quick examples: - If b = 0, then a > 1. - If a = 5, then b < 4.
