This example demonstrates the concept of combining like terms in algebra, visualized through the quantities of fruits in different baskets; core math concepts include algebraic operations, like terms identification, and cross-group combination; GeoGebra commands and objects used in construction are LaTeX, Polygon, PointIn, Join, Zip, Textfield, TableText, and objects like numBasket3bananas, numBasket2oranges, etc., for creating and displaying fruit baskets and quantities; suitable for middle school mathematics teaching to help students understand and master the skill of combining like terms.
