Составить сочинение на языке на тему 《i love math》

I don't think that many people can say that they love math, but I'm one of those people. For me math is not only a subject, it is my everyday exercise. Some people go to the gym, some people run in the mornings and I solve math problems before I go to bed to exercise my brain. I do that to keep my brain working since the brain is just another muscle in our body and you can't expect a muscle to stay  fit if you don't exercise. Therefore, I exercise everyday to keep my brain fit.
