This document contains 10 programming exercises in Gambas, a visual programming language. The exercises cover basic concepts like variables, conditionals, loops, functions, objects, and graphical user interfaces. They include calculating sums, finding the largest of 3 numbers, validating ID numbers, calculating factorials, and creating a simple calculator application. The exercises demonstrate how to perform common programming tasks in Gambas.
