Anonymous users2024-02-09The table is under pressure! Elementary school math case
I was also full of mistakes in elementary school, and I didn't find any mistakes after watching an addition operation several times.
When you look back on these past events, you will find that it is also very good, and there are some things to recall. Ha ha!!!
It doesn't matter if you make mistakes, just know how to correct them, you don't need to take learning too seriously, learning is to let you master knowledge, not to enslave you, you don't need everything to be perfect.
When you go into society, you can't succeed at one time, just like a programmer, you can't write a good program at one time, you have to go through repeated debugging. o( o haha

Anonymous users2024-02-06Is it an application problem or a simple arithmetic problem?
If it's purely an arithmetic problem, this can only be practiced more, and there is no other good way.
If it is an application question, you can find one or two basic questions first, and have a comprehensive understanding and analysis of the topic, so that you will be more handy when you encounter the same type of question in the future.

Anonymous users2024-01-31As we all know, primary school students often write half of the wrong numbers or words, write half of the sentences without the tone, miss half of the questions, forget the punctuation marks and do not fill in the final number. In fact, all of them will, but they are a little careless and careless. Here's how we can help elementary school students get rid of this careless problem.
1.Exercise for elementary school students to concentrate.
In order to overcome carelessness, elementary school students must learn to always focus on the work to be done. Some parents, regardless of whether their children are learning or not, turn on the TV, or play cards and mahjong by themselves, these practices will cause interference to children and make them unable to concentrate on learning. Over time, children begin to be frizzy and develop the bad habit of "single-mindedness".
Therefore, parents should create a quiet learning environment for their children while they are studying.
2.Primary school students are more aware of the importance of learning.
When Hu Yin's attack on people faces more difficult problems, they will pay more attention to it psychologically, resulting in the brain thinking is not easy to be disturbed, so it is not easy to make mistakes; On the other hand, they do not pay much attention to the easier problems, and their thoughts are easily disturbed, so they are more likely to make mistakes. Therefore, if you pay attention to any problem, you will not be careless and take it lightly, and you can also consciously overcome the distraction, which will help to overcome the problem of carelessness.

Anonymous users2024-01-29Master Zhang produces 5 parts per minute, Master Wang produces 4 parts per minute, and the number of parts that Master Zhang and Master Wang plan to produce is 720 each.
When Master Zhang produced 400 pieces, Master Wang produced 320 pieces. If Master Zhang produces 18 minutes later than Master Wang, then Master Wang produces half the time (360 pieces, 360 4 = 90 minutes), and Master Zhang produces 360 pieces in 72 minutes. And when Master Zhang completes the task, Master Wang 360-4*72=360-308=72, that is, there are still 72 parts left to complete the task.

Anonymous users2024-01-28If the number of parts produced by Master Zhang is x, then Master Wang is 5x 3
5x/3-55）/（x+55）=3/4
Just solve the equations. 3（x+55）=4（5x/3-55）3x+165=20x/3-220
11x/3=385
x=1055x/3=175
105+175=280 Satisfied!

Assuming that the speed of A and B is that the distance between the two stations is Z, the first time is after the t1 time, and the second time is T2, when the first encounter, A and B have traveled the whole distance Z, because the first time they meet 12 kilometers west of the midpoint, and it is 12kmt1=z 2-12 xThe second meeting place is 20 kilometers away from the East Railway Station, and A has already traveled Z+20kmT2=Z+20 x The system of equations (Z 2-12) (x+y) x=Z can be obtained from the above; (x+y)(z+20) x=3zEquation2 Equation 1 yields (2z+40) (z-24)=3 and z=112
