Math is poor! What s the supplement?? Kneel and beg!

Listen carefully in class, the basic skills of mathematics are solid, that is, the things in the textbook must be understood, and the general exercises are derived from the example problems in the book, so the textbook is the key. A set of more formal test papers must be estimated to be able to pass everyone.,100 points of test papers, everything in the textbook is understood.,If you can't draw inferences.,It's no problem to pass.,75 points is no problem if you understand the exercises after class.。。。 Usually practice more exercises, and if you don't know what you do, write them down in a notebook, understand them thoroughly, and take them out more often.

A little trick when doing the question, while looking at the question and associating it, look at a sentence to list the obvious and hidden known conditions told by this sentence, after reading the question backwards from the question, it is very good to write the answer, even if you can't get the final answer, as long as you have certified that you have thought about it, the teacher will be able to keep up with the certification when explaining, and you will really understand the problem thoroughly. . . You can do something similar in the future. Come on.

Look at the theorem knowledge in the books, first understand it and then do example problems and after-class exercises, and you must listen carefully to the lectures in class, understand what you have learned, and your grades will slowly improve after a long time.

What grade is it? Generally speaking, poor math is due to a lack of problems. There aren't many things that can be applied to mathematics.

Generally speaking, find some typical questions, do some every day, then memorize them, stick to them every day, and after a period of time, you will find that they are very effective. The basic question types in mathematics are similar, and there are only so many test points. You can try.

You can go to cram school, but you have to do more! The main thing is that you have to like it from the bottom of your heart!

In fact, mathematics is not difficult to learn, as long as you have a certain foundation, add more exercises, and gradually sublimate yourself from the simple and easy to understand.

Geometry requires a lot of observations of images and formulas.

Learn the learning methods of the classmates next to you and learn from each other's strengths.

The plastics plant plans to produce 960 plastic boxes, of which 384 are produced in 4 units, and the rest will be completed in a few days. What is the judgment language?

There are x letterheads and y envelopes.

The General Affairs Office used all envelopes y, and used x-50 letterheads, one letter, so y=x-50

The Academic Affairs Office uses up envelopes Y-50, all envelopes x and one envelope three notes, so Y-50=x 3

Simultaneous equations, solved x=150, y=100

Let envelopes x rafts y x+50=y y 3+50=x find y=150 x=100

If there are x envelopes, then there are x+50 envelopes.

x-50)/1=(x+50)/3

3(x-50)=x+50

3x-150=x+50

2x=200

x = 100 envelopes, 150 for rafts.

If you don't understand, you can ask.

Let the trees to be planted at the beginning be x in each row, and the total number of original saplings can be obtained as x +25, and the total number of (x+1) -2 can be seen from the second condition, so x +25 = (x+1) -2. Dismiss x=13. A total of 194 saplings can be calculated.

The 6 of us went out together, and then each contributed 300 yuan.

6x300=1800 (yuan).

But I booked a car and bought things first, and spent 1,100 yuan.

1800-1100 = 700 (yuan).

Then I bought another ticket and spent 145 yuan.

700-145 = 555 (yuan).

How much did one person cost?

1100+145) 6=RMB).

How much is left in each person?

555 6 = yuan).

So, one person spent yuan, and each person had yuan left.

A total of 1245 was spent, divided by 6, that is, each person spent yuan;

A total of 1800, 1800-1245 = 555, and then divided by 6, that is, each person has the remaining yuan.

A total of 1100 + 145 = 1245 yuan was spent. There are 6 people in total, so each person spends 1245 6 = yuan.

Then each person paid 300 (did you put in the 300 you paid yourself?) ), should be refunded.

And your tickets are 145 to 6 are divided by constantly, how much are the tickets per person?

The total cost is 1245 yuan, 1245 6=, no one, left.

It doesn't matter, 24 hours a day, 120 hours is 5 days, 120 24 = 5

A day is equal to 24 hours.

120 hours, i.e. 120 divided by 24=5 days, is five days.

5 days...

Since there are 24 hours in a day, dividing 120 by 24 equals 5 days

Hey hey

24 hours a day.

120 hours divided by 24 hours is a total of days.

Equation: 120 divided by 24 = 5 (days).

That's 5 days.

LZ is 5 days, as for how to calculate it, I don't think it goes without saying, you know for sure.

I want to believe that you are not a stupid child, and you are quite self-motivated, I hope your math will gradually get better.

In the words of our teacher, it takes 5 more days to do the questions.
