I would like to ask you two questions, one in English and the other in mathematics, which is not dif

This needs to be very detailed, so send me a message if you need it.

The formula for the series.

Equal: an=a1+(n-1)*d, where d is that difference.

Equal area: an=a1*q (n-1), where q is that equal area.

It's a phrase. Equal: an=a1+(n-1)*d, where d is that difference.

Equal area: an=a1*q (n-1), where q is that equal area.

I'm in elementary school, how do I know?

Mathematics: Patience + Perseverance + Perseverance.

Changes: High school mathematics has made a qualitative leap compared with junior high school in terms of depth of knowledge and ability requirements, and the content is difficult, abstract, and has high requirements for analytical ability. Therefore, it is normal for you to smile and drop your grades after entering high school, so you don't have to worry about not getting high scores.

Of course, attitude is everything, and with patience, perseverance and perseverance, I believe that you can learn high school mathematics well.

Method: Learning to listen to lectures is very important in high school mathematics learning, when listening to the teacher's analysis of problems, you should pay attention to the ideas and methods, master the principles, and gain in one class. Note-taking can improve the efficiency of listening to lectures, but it should not affect listening to lectures.

If you find it difficult to listen to the class, you should do a good job of preparing for the class. The essence of learning mathematics is to learn to solve problems, and to learn to ask a few more whys. Through repeated thinking, the knowledge after understanding can truly become one's own.

In the study of science, it is necessary to establish a sense of self-study. In addition, doing more practice will help you learn math well, but you should emphasize "appropriateness" rather than doing more and doing more tactics. English:

Grammar and vocabulary are the two main elements.

Change: After entering high school, the content of English textbooks has increased and spanned, unlike junior high school, where you can repeatedly practice the knowledge points to complete mastery in one class, so you should pay more attention to self-study and learn from the past. High school English focuses on the development of reading skills, and it is necessary to flexibly apply the knowledge learned to the understanding of language and texts.

This requires a lot of independent reading in addition to a certain amount of practice.

Method: In the first year of high school, the focus is on cultivating interest, establishing confidence, guessing, exercising listening and speaking skills, mastering several important grammar points, mastering basic reading methods, and cultivating good study habits. In the second year of high school, adhere to the connection between listening and speaking, focus on expanding the number of words and reading, and improve the comprehensive use of language.

In the third year of high school, improve the accuracy and comprehensiveness of language knowledge, and improve problem-solving skills and test-taking ability through appropriate training. In addition, grammar and vocabulary are the two main elements of learning English. "The theory of universal uniqueness of grammar" and "the theory of uselessness of grammar" are not advisable, and grammar should insist on learning in combination with context.

For the learning of vocabulary, we should adhere to the principle of not leaving sentences and sentences, and actively memorize them in reading. When memorizing words for the first time, it is encouraged to combine phonics rules to achieve the realm of "reading their sounds and knowing their shapes". In addition, it is necessary to pay attention to the consolidation of listening and speaking skills, through memorizing classic texts and actively participating in activities such as English corners.

You don't have to worry about mathematics, the focus is on understanding, do more examples, and you will really understand.

However, the concept class is next to the rise of things, and the belief must be remembered.

English, this is still memorized, this is not slippery.
