Focus on structure and logic in numbers: order of operations, factoring, GCF/LCM, integer properties, and basic linear equations/inequalities. Difficulty ramps gradually to build confidence without overwhelm.
Short, focused explanations highlight the shortest path to the answer. Use hints and replays to convert mistakes into fast, reliable methods for exam day.
