Hello, my name is Arbhy Adityabrahma and I’m from Indonesia. You can call me Arbhy. I’m always feel bad at math. Back then when I was on my high school, my teacher be like just gave me some compliment because my diligent, but never about my skill itself. I’m realizing how bad am I; never got so-high score and always stuck in minimum score or less no matter how long time that I’ve spent for learning math. So, I wanna make a change for myself and also for the better future. For me, math isn’t just about math. It’s one of skills that can be implemented to any aspect of life.
