This is the first workshop, Linear Algebra, Real Analysis and Topology, organized by the Mathematical Association of Cambodia (MAC). We aim to prioritize joyful learning and active interaction to inspire and help participants grasp the foundation of mathematics through our enthusiasm for doing mathematics. Our keynote speakers are willing to dedicate their time and energy to introduce abstract mathematics not usually seen by non-specialists and to change attitudes about what mathematics is, what it is for, and how it works. After this workshop, we hope all the intended participants have great joy in exploring mathematics as much as we do, and that becomes their driving force for pursuing more advanced mathematics, further and further, more and more deeply.
