I launched this Mag to demonstrate to my then-5-year-old son that math can be a fun and fascinating subject, rather than boring and mundane. As a child, I became drawn to math and science through reading intriguing stories, and I felt that there was a lack of similar materials available for young kids. So I decided to create a Mag to showcase the wonder of math to my son. The primary goal is not to provide children with specific math knowledge, but to immerse them in the enjoyment of math. If we can connect math with the word "fun" in our kids' minds, then we will have accomplished our objective. After all, interest is the most effective teacher.
