Overview
Learn the concept through terminology and working:
Terminology and Concept
Terminology: use Calculated controls, Calculated, controls, Expressions in controls produce row calculations precisely. Define each term before using it in an explanation, algorithm, program, or comparison.
Examples Expressions in controls produce row calculations, group totals, grand totals, dates, and page numbers.
Working and Application
Working method: first identify the input or starting state for calculated controls; then apply the rule or process in a clear order; finally inspect the output, test an edge case, and explain any limitation.
Examples Example: apply calculated controls to a small school, home, or software problem and trace the result.
