About math multiple choice and fill in the blank questions, math fill in the blank and multiple choi

After the calculation problem is solved, if you still make mistakes, you may fall into the trap of the questioner. If you can grasp what the teacher wants to examine from the perspective of the person who wrote the question, it is not easy to make such a mistake. There is a misunderstanding that needs to be pointed out, that is, if it is not a calculation error, it cannot be regarded as "carelessness", and it is necessary to pay attention to such a problem.

The question is small, but the score is not small!

If you want to make a big improvement in the remaining days, I don't recommend you to do new questions, I suggest that you can turn over the questions you have done before and missed them a few times, not to see how to do it, but to see how it went wrong, analyze the cause of the mistake and don't make similar mistakes again.

If parents have time, you can ask them to cooperate with you to sort out these mistakes, such as copying the questions again (without answers) and doing them again.

In addition, the college entrance examination is getting closer and closer, and you should also be reminded that you have time to complete some sets of questions according to the time of the college entrance examination, so as to simulate the real feeling of the college entrance examination.

The college entrance examination is approaching, pay attention to your body, these days are cold and warm.

I hope it helps you, I wish you the title of the gold list!!

There are two situations where simple questions are wrong, one is carelessness, and the other is not good enough. It's like asking you how many 1+2=how many you are, no matter how careless you are, you won't be wrong.

It is recommended to use the elimination method to do the multiple-choice questions, even if you know the correct answer, you must first judge the other options** wrong, so that it will generally not be wrong.

There is no good way to fill in the blanks, you can do the answer and bring it back to the original question to check it again.

Simple will do wrong things, which means that you are careless. So you should check it again after you finish it.

It's better to check a few more times, be a little more patient, if you are impatient, you will miss a lot of chances to score.

You should be in the sprint for the high school entrance examination or high school. I used to make a very simple question wrong, and I regretted it afterwards, and the multiple-choice questions should use the elimination method, and when you choose, you should use the most basic to check, and then do three multiple-choice questions every day, pick some typical questions to practice, only three! If you practice the sense of the question, you can also practice the carefulness, and then the fill-in-the-blank questions will not be careless.

Fill-in-the-blank questions are Thursdays.

Select the topics entitled C, B, D, A, C

1. It can be from the title.

Know: a=2bb=3ca=6c

a+b-2c=7c

2. (a-10)+(a+8)=0 2a-2=0 a8= m min (multiplied by 10 to the third power).

Question 1: a-2b=0 b-3c=0

a=2b b=3c

So, a+b-2c=2b+3c-2c=2 3c+3c-2c=7c choose b

Question 2: Because a-10+a+8=0

So a=1

Question 3: 30km = 30,000m

Speed = distance time.

The velocity is equal to 30000 8=

Solution 1: a-2b|≥0

b-3c) and |a-2b|+(b-3c) =0 a-2b=0 and b-3c=o, i.e., a=2b, b=3c a+b-2c=7c, so b

Solution 2: a-10 and a+8 are inverses of each other (a-10)=-(a+8).

a=1Solution 3: One-way running time represents "the time it takes for the train to run once" t=8min

And s = 30km = 30000 meters.

Speed v=s t=3750m min=

The bus runs south on Wuyi Road, continues to drive 900m to CITIC Plaza after reaching the department store, and then drives 1200m west to reach the Cultural Palace, the shortest distance between the department store and the Municipal Cultural Center is 1500m.

2. The square of the hypotenuse of a right triangle is equal to 2 times the product of the two corner edges, and this triangle has an acute angle of (d).

A, 15° B, 30° C, 60° D, 45° 3, the bottom edge is 24cm, and the waist length of the isosceles triangle with a height of 9cm on the bottom edge is (C) A, 12cm B, 14cm C, 15cm D, 16cm

1。There is a problem with the options of this question, you probably wrote it incorrectly, and the correct order should be a a a -a -(1 a).

304=4 76=(3+1) (75+1)(75 is not prime, rounded) 304=2 152=(1+1) (151+1)(1 is not prime, rounded) 304=8 38=(7+1) (37+1)304=16 19=(15+1) (18+1)(15 is not a prime rounded).
