Fill-in-the-blank math questions in the college entrance examination should be carefully examined and answered slowly. Be more careful when solving the fill-in-the-blank questions, and try to do it right once. Fill in the blanks can also make a mountain out of a molehill, so we should pay special attention to the application of special case solving methods and the combination of numbers and shapes when solving the blanks.

Most of the multiple-choice questions in mathematics answering methods are middle-low sub-questions, so we must strive for more points or full marks. Answer the multiple-choice questions slowly and quickly. Therefore, in addition to directly solving multiple-choice questions, we must try our best to make a mountain out of a molehill and try our best to be clever. The common methods of answering multiple-choice questions are: combining numbers with shapes (making sketches according to the meaning of the questions and solving problems by combining images); Special case test method (replacing the general conditions in problem setting with special cases and drawing conclusions); Screening method (according to the different options, select special circumstances from the options to test whether it meets the meaning of the question); Equivalent transformation method (changing strangeness into familiarity); Structural method (such as Li Ji's "cut-and-fill" thought) In addition, you should learn to give up temporarily when answering multiple-choice questions.

Interval method is a method in the mathematics of college entrance examination, also called exclusion method, which relies on roughly calculated data or guesses some data. For example, how many angles are given to a topic, 30 and 90. Obviously, the answer must be 90 30 degrees, 120 plus or minus 30 degrees. Or some answers related to 30, 60 or 90 degrees.

Coordinate method, if you can't find ideas in some graphic problems, you can use the proportional method first, and then use the coordinate method. You can directly find the coordinates of two points, regardless of any trigonometric function, and directly bring in the high school function to find the angle (cos formula), vertical formula, length formula and tangent formula. Go straight to Huanglong without looking for an angle to do anything troublesome.

Proportional method, this method is very simple and rogue. If you encounter graphics problems, mark the known first, measure the unknown with a protractor, and then it is time to witness the miracle! Measure the proportional relationship between two solid lines with a ruler, and then estimate the length of a known side approximately by the ratio of that side.
