rapid calculations

Rapid calculations refer to the ability to quickly and accurately perform mathematical computations, often through mental strategies or practiced techniques. This skill involves recognizing patterns, breaking problems into simpler parts, and using shortcuts to save time. For example, estimating sums, multiplying by numbers like 5 or 9, or quickly squaring close numbers. Developing this skill improves efficiency in everyday tasks, professional work, and competitive environments, relying on practice and understanding of mathematical principles to minimize reliance on paper or calculators.
