請高手指出文法和用詞的錯誤

This is a new one, because i don't understand what are you talking about.

I love math very much, because i don't have to memorize as many stuffs as other subjects. I only have to understand the principle then i can solve the problem. It's extremely entertaining.

I really like disciplines which related to numbers, such as mathematics. This is because mathematics is unlike others studies which require you to memorise large amount of materials. As long you understood the operational method, mathematics can solve the problems for you. I find this extremely interesting.
