Mathematical puzzle skills 1

Mongolian body is also a science. I am a senior three student, and the success rate of math puzzles is over 70%. First of all, make it clear that the problem can't be pure, and you must have the effect of seeing the problem after reading it. If you can't do it after reading the question, look at the options first, some can be excluded, and then analyze according to the conditions of the question, and some options may be excluded, which will be much easier.

If you can't rule out one, then consider the option. If there is an answer about extracurricular activities (which rarely appears in class), it is probably that one. If the number of options is 4, usually the second largest option is the correct option. Looking at the options alone, there are generally more BD and less A. One more thing, don't change it after you choose it unless you are more than 90% sure.

As far as I know, the first question in mathematics is generally not A; The last question will not be a; The answers to multiple-choice questions are evenly distributed; Fill in the blanks not only with 0 or1; If the answer has a root sign, don't choose; If the answer is 1, select; When all three answers are yes, choose the right one; When one is positive x and the other is negative x, choose one of them; The topic looks simple, so the answer is complicated, and vice versa; What to choose in the previous question, what to choose in this question, if there are three identical ones in succession, it is not; When none of the above is practical, choose B.

In the calculation, you should write an answer first. If the number of options is 4, usually the second largest option is the correct option. Looking at the options alone, there are generally more BD and less A. One more thing, don't change it after you choose it unless you are more than 90% sure. Fill in the blanks according to the selection of related graphics can take special values.

You can't make a big problem, you can't use the conclusions you ask, and you can't deduce the conclusions you can think of according to the conditions. Usually you have points. If you are lucky, you can get more than half of 1. Fill in the blanks carefully, jump without thinking for 2 minutes, don't write the most possible answer, the chance of getting it right is not small.

1. If the answer has a root symbol, please do not select it.

2. If the answer is 1, please select.

3. When all three answers are yes, choose the right one.

4. When one is positive X and the other is negative X, choose one of them.

If the question looks simple, then the answer is complex, and vice versa.

6. If you choose the previous question and this question, it is not suitable to do this article if three identical ones appear in succession.

7. A good answer depends on your eyes.

8. when none of the above is practical, choose B.

Mathematics is reexamined from easy to difficult.

Fill in the blanks: be careful again. In mathematics subjective questions, fill-in-the-blank questions are not like the big questions behind, and need specific problem-solving steps. It only requires candidates to give a final answer. This requires candidates to be more careful in answering questions and solve problems step by step.

Big problem: the steps need to be clear. In the process of correcting big questions (calculation questions, proof questions), the main points and conclusions of the process are generally given separately. Therefore, candidates should write down the steps clearly when answering questions, so that they can not only get the step marks, but also help their later investigation. Otherwise, it's like filling in the blanks. If the answer is wrong, there is no score.

Self: Positioning needs rationality In recent years, there have been some strange phenomena in the college entrance examination, that is, some students usually perform well, but their papers just can't get up. This is mainly because there is something wrong with students' own positioning. Because these candidates spend too much time on difficult questions, the probability of making mistakes on easy questions is greatly increased. In fact, the proportion of difficult questions in the exam is only 20%. Therefore, candidates should not have the irrational idea that "the question must be chewed up" when answering questions. As long as you get all the easy questions honestly, the scores in the exam will not be very low.

Answer: Be bold again. If you are not sure, you'd better not erase the original answer. Both methods can be written on the test paper. The marking teacher will generally give points according to the method of high scores.
