Tri Subiantoro

I am named Tri Subiantoro. The making of this channel is intended to share in terms of education.
Making my first video about learning high school mathematics / MA.
In the future I will make a learning video for junior high school / junior high school / elementary school
In addition to making videos about the basic concepts of mathematics, discussions on national level examinations are also made (both national exams and state higher education entrance exams).
