The above math knowledge is relatively simple, and the color is blue. The following mathematical knowledge is getting more and more difficult, so the color is getting deeper and deeper, just like the abyss at the bottom of the sea, so it is also called mathematical abyss map. Before the first grade of primary school, many children learned to count, such as counting families and apples. The above is the introduction and the simplest math knowledge.
Elementary school just started to learn addition, subtraction, multiplication and division and some simple geometry knowledge. For example, four operations and the formulas of perimeter and area of basic figures such as squares, rectangles and circles. Elementary school begins to learn advanced calculation of addition, subtraction, multiplication and division, as well as more complicated geometry and application problems. At this time, the average student has little problem, with a full score of 100 and more than 90 points in mathematics. However, since junior high school, the difficulty of mathematics has gradually increased, and there have been negative numbers, multiple equations, powers, roots, factors and other knowledge.
High school mathematics and junior high school mathematics are completely two grades. Many students with more than 70 points in junior high school mathematics can only get more than 40 points in senior high school. It's not that they don't work hard, but that many people's IQ can't keep up with the pace of high school mathematics. High school mathematics began to learn all kinds of difficult functions, including exponential function, logarithmic function, trigonometric function and so on. Geometry, on the other hand, is directly promoted to several levels on the basis of junior high school. Analytic geometry and solid geometry drive most students crazy.
It is not difficult to master the skills to learn mathematics;
First of all, we must master the basic knowledge points. For example, some basic formulas must be remembered clearly. Mathematics is nothing more than some formulas as a framework, and there is a framework. Next, just like building a house, it should be built according to his model. Be careful during the period, because the numbers are sensitive and will be lost a little.
Second, for geometry problems, touch more graphics, mark the information in the problem and related graphics on the map, sketch more and calculate more. Be sure to pay attention to the decimal point and calculate carefully. When you encounter a problem that you can't do in the examination room, just go around and do the problem that you can't do, and do it again when you have time.
