Integer Addition Demo: Conditional Logic in GeoGebra

①This GeoGebra example demonstrates integer addition through an interactive interface, using conditional (If) commands to dynamically show results of adding various integers. ②Core mathematical concepts include integer arithmetic, addition rules for positive and negative numbers, and the use of conditional logic in mathematical modeling. ③Construction details: The summary lists the If command and objects a, b, c, text1, text2, text3—likely representing two addends (a, b), the sum (c), and text labels for displaying the expression and result. The conditional logic handles different sign combinations (e.g., positive+negative, negative+negative). ④Suitable for upper elementary to middle school students learning integer operations, as well as for teachers demonstrating addition rules or students exploring number patterns independently.
