Actually I think that maths for me, it should be very difficult. You know, I couldn't learn it well. Probably I have no interests, or let us say I am not that clever enough or smart enough. For example, when I was in my primary school, I couldn't learn it well. Till now, it has been a long time. But I think maths in my life should be very important among all the subjects, such as Chinese or English or other subjects, I think maths should be the most important one. But for me I couldn't learn it well. That is it.
