This activity introduces students to analog computing using a small analog circuit evaluator. By building simple circuits, students solve linear equations and basic differential equations in a hands-on way. Some exercises are related to simple mechanical problems, such as motion or oscillations. The activity uses operational amplifiers to represent mathematical operations such as addition, integration, or differentiation. In this way, students can see how mathematics is transformed into real electrical signals. Direct experimentation facilitates the understanding of abstract concepts. It also encourages scientific thinking and the connection between physics, mathematics, and technology. The activity offers a first intuitive approach to the concept of analog computing.
