What will I learn?

The Integer Parts Course gives you a fast, practical command of floor, ceiling, and fractional part functions. You will master core properties, key inequalities, and efficient manipulations, then apply them to sums, counting arguments, divisibility, and interval problems. Short proofs, worked examples, and quick checks help you avoid common errors and write clear, concise solutions with confidence.
