WELCOME
to my blog
Welcome to my Math Blog! I'm Hien Vinh, a high school student. You not only can find in this blog some interesting Math Posts but can also find my biggest dedication: my self-written Math Book.
I would be very glad if you could share with me some stories, aspects of Math in real life, or solutions to problems that I find interesting. Don't hesitate to share comments, thoughts, and ideas if you find out something fascinating.








There are numerous Math Competitions in my secondary school where students spend weekend mornings participating in different rounds. Therefore, I decided to choose most 4 worthwhile international competitions and write it in a book where students can use the problems as reference to ignite their real passion for Math without having to enroll in too many contests.
In this book, I have collected question papers and both self-written and chose the most accurate solutions for each problem. Lately, it has been proofread and printed with allowances for 200 students in 2 Math Hanoi Educational Centers.

This is where I share not only my thoughts but also my feelings about math in life through articles
