The influence of early mathematics learning and learning motivation on student learning outcomes is very significant [1]. Students' numeracy literacy skills need to be supported by the ability to learn mathematics as early as possible. Advanced mathematics learning needs to be supported by good arithmetic skills. Every learning process is expected to produce good learning outcomes. Conventional mathematics learning is difficult for low-level students to understand. Guidebooks that are in accordance with the learning curriculum tend to present mathematical concepts that are textual. In order for mathematics learning to be more interesting for students, it is necessary to develop learning media that are easily accessible to students and educators. One application that can be used is interactive Powerpoint [2]. In this community service, a learning media about arithmetic was developed that underlies every logic of calculation in advanced mathematics.
