Passage 39 Many people have difficulty in studying mathematics. Sometimes their difficulty stems from the psychological idea that they are "not good at math". (39) It has been demonstrated that many times that it is often this idea that is causing their problems rather than any lack of skill in mathematics. The best way to deal with this problem is to tell yourself that math involves using the same numbers you have been using all your life and that you know them as well as anyone else. Then set your mind to learning how they are used in the particular part of mathematics you are studying. Many schools offer "math anxiety" courses which are designed to help people overcome their fear of math. Another problem many people encounter is that in mathematics, unlike some other subjects you may have studied, the material has a very important sequence or order. If you do not understand a section of mathematics text, it is no use going on to the next section. Many sections of math books are based on information presented earlier, so it is essential that you understand a section before going on to the next. Sometimes students in mathematics courses do not read the written material in the text but assume that the instructor will tell them what they need to know. This can cause them serious problems, since many instructors assume that students have read the text before coming to class. The written sections of mathematics textbooks contain much valuable information.
A．to study math wellB．to realize the importance of mathC．to overcome your fear of mathD．learn more about math
