Mathematics is basically a science whose main purpose is to direct the flow of thinking according to the rules of logic. In learning mathematics, teachers are expected to be able to attract the attention of students to be happy in learning mathematics. In the learning process the teacher only uses old worksheets and has not used learning media. As can be seen from the teacher still using the lecture method accompanied by assignments. This has an impact on the inability of students to solve problems, so it is not uncommon for teachers to repeat the explanation of the material.
