Laskukaavio

Laskukaavio, literally meaning a calculation diagram, is a diagrammatic representation used to illustrate the steps and dependencies involved in a calculation or computational process. In Finnish contexts, laskukaaviot are commonly employed in education to show problem-solving procedures and in professional settings to plan calculations in fields such as accounting, engineering, or programming. The aim is to make the sequence of operations clear and easy to communicate.

A laskukaavio typically uses familiar diagrammatic elements found in flowcharts. Start and end points mark the process boundaries, boxes denote arithmetic steps or formulas, parallelograms indicate input or output, and diamonds represent decision points. Arrows show the flow of control and data, while notes or labels may specify formulas, units, or conditions. The level of detail can vary from simple stepwise procedures to more formal representations of complex calculations.

Common uses include teaching mathematical procedures, validating calculation logic, documenting computational processes for audits, and planning software or spreadsheet algorithms. Because it focuses on calculations rather than generic program logic, laskukaaviot emphasize data flow and numerical operations, aiding error detection and optimization.

Example: To compute the average of three numbers a, b, c, a laskukaavio might show inputs for a, b, and c, a step for summing them (sum = a + b + c), a step for dividing by 3 (average = sum / 3), and an output step for the result. This illustrates the calculation sequence in a concise, visual form. Related concepts include vuokaavio (flowchart) and other computational diagrams.
