Logic, sets, and maps, which are essential basic languages for learning any field of mathematics or informatics, are explained in terms of the basics and the parts where beginners (e.g., first-year university students) tend to get stuck.

For sets, we will explain the definition of relationships between two sets (such as inclusive relation and identity). For maps, we will explain the definitions of surjection, injection, and bijection.
