Math problems have a standardized writing format, and the most standardized writing format is the writing format of reference answers. It's absolutely right to write like a reference answer. The following are some writing points of the summary of mathematical problem format: 1, divide the big problem area, and the blank space for junior and senior high school homework is generally horizontal, so I personally suggest dividing it into several small squares with vertical lines and writing it from top to bottom and from left to right in turn. The college entrance examination is generally a vertical answer area, as long as it is written from top to bottom. 2. The estimation of font size is easily overlooked. Generally speaking, in addition to trigonometric functions, big questions in senior high schools need a lot of calculations, so please try to use clear big questions. Simple questions such as trigonometric functions, you can appropriately enlarge the number of words, and it is best to finish writing the answer font, and the answer space is close to running out. Don't write too big, resulting in insufficient space, and don't write too small, leaving too much space. 3. Standard format. For example, there are multiple small questions in a big question. Write a small question in the first line and answer the question after writing the second line. Try to operate only one step per line, or write an equation, and sometimes you will encounter relevant conditions, such as congruent triangles's proof. Please use braces and other necessary symbols, occupying three lines, each line writing a condition, the last line writing a conclusion, and brackets indicating the type. Never solve the problem of writing directly with one line of words. If you make a mistake, you will cross out the whole word. If you make too many mistakes, you will cross out all the lines. Don't save trouble, which will cause the roll surface to change too much. When you write, sit up straight and write on the horizontal line. This is a cliche. I don't want to say more. Don't write all the steps on the test paper. Except for the calculation questions, all the calculation steps of other questions are not recommended to be written in the answer area. For example, to solve a binary linear equation, you can write this equation in the first and second lines, then draw an arrow and write the result directly in the third and fourth lines. The problem-solving teacher looks at the key steps, not all the steps. If you don't write, you won't be in cut class.
