Sure is 2. I like mathematic very much. Actually not only mathematic but I like all subjects that involve calculation. Most of the people think that guy usually better in calculation and girl better in memorising. I think this is not really true because I am the top student in my class for mathematics and science in my secondary school. Even now I am quite top in mathematics.
