In mathematics, there are many theorems that are built from previously agreed definitions. A student who learns mathematics will naturally be trained to honestly use a definition or theorem to prove the next theorem. This verification process also trains openness to accept criticism and suggestions from other people so that they obtain valid and accountable evidence.

The use of definitions, lemmas and theorems will train the consistency of students who study them. Inconsistencies will cause the final results to be wrong or even contradictory.
This was conveyed by UNNES Semarang Mathematics lecturer, S. B. Waluya at the National Seminar on Mathematics and Mathematics Education with the theme Contribution of Mathematics and Mathematics Education in Building the Character of Teachers and Students, Saturday 10/11 at FMIPA UNY.

It is said that students will become self-confident if they can understand and use mathematics as well as possible and students can understand and make sense. On the other hand, if you cannot master it you can become frustrated/desperate.

Lim Chap Sam from Universiti Sains Malaysia explained that the large contribution of mathematics education in shaping students' character was laid as the basis for the Ministry of Education of Singapore and Malaysia in formulating the curriculum. The education curriculum in Singapore itself outlines the role of Mathematics in two big points, developing children's positive attitudes, including a sense of self-confidence, finding ways to learn in a fun and persistent way as well as fostering reasoning, curiosity and intellectual powers.

“Students who have great curiosity have more creative and innovative ways of thinking. "Meanwhile, creativity and innovation are the characters needed to build a nation in the future," he continued.

Meanwhile, Jamilah Bondan WIjayanti from FMIPA UNY, said that mathematics learning pays attention to the human side of students, which is known as Humane Mathematics Learning. The side in question is the involvement of the brain and emotions in every learning activity. By carrying out humanistic learning plus sincerity and enthusiasm to be willing to continue learning, a teacher/lecturer will make a real contribution to the development of national character through building his own character and the character of his students.
