When I was in high school, I was pretty good with Math especially algebra, pre-calculus, and geometry. I was number one in Math s classes during my high school freshment to my senior year. I helped and mentor a lot of friends. In college, I was pretty good in calculus, linear algebra, and differential equations. I used to tutor Math in college. When I studied electric engineer, I used a lot of Math for engineering problem. Now as an engineer I still used Math for my daily task.
