It is really difficult for some students to learn and, to be exact, hard to understand, when they start their teaching of rational numbers at the beginning of the seventh grade What causes it? Frankly, the reasons for the above phenomena and problems are very complicated, but I think the students did not understand the meaning of mathematical symbols is affirmative. Just a short 45 minutes to allow students to remember a calculation step, master A skill may be, but a mess, a write wrong to make both teachers and students are much harmed below the beginning of the seventh grade teaching "absolute value
