1, pronounced: numbers should be capitalized, such as numbers written by one, two, three, four, five, six, seven, eight and nine, such as: 58, pronounced: 58.

2. Writing: refers to writing with lowercase Arabic numerals, such as 1, 2, 3, 4, 5, 6, 7, 8, 9, such as seventy-three, and writing: 73.

3. In math homework, reading means writing reading in Chinese characters, and writing means using Arabic numerals to indicate the number to be read.

4. Reading from the high bit to the low bit: read one level at a time, the zero at the end of each level is not read, and the remaining digits only read one zero for several consecutive zeros.

5. Writing of integers: from high to low, writing step by step. If there is no unit on any number, write 0 on that number. For example, 1203.4 should be read as: 1203.4, that is, read from the highest bit 1, write from the highest bit 1, and write from high to low.

6. Reading is to express numbers in words, such as 1203.4. Reading is to write a number 1203.4, which means to represent a number with numbers and symbols.

Learn primary school mathematics well;

1, consolidate the foundation

Including concepts, formulas and theorems. If you can use yourself, find someone to talk to him once, and he will understand, and so will you. This is the same as the topic. I will, but if I tell others, I may not be able to make them understand.

2. Use what you have learned as a tool to solve problems.

Little knowledge was learned at the beginning of primary school, so everything should be done step by step. Take the calculation before the second grade, which basically belongs to this, and the calculation at the same level goes from left to right.

Therefore, we need to use what we have learned as a tool for examining questions, rather than just saying what we have learned. Just as we have learned to add several identical numbers, we will use multiplication to calculate them quickly and accurately. After the fifth grade, we learned to raise the common factor and learn to construct the same number flexibly. These are the tools that we learn and use flexibly.

3. Summary

This is what many students lack. A problem can be done, in other words, it may not be done. In fact, this situation belongs to, do not summarize, do not know how to be flexible. You can't infer from one topic to another. In fact, there are many similar problems, and we can relate them, so that the learning efficiency will naturally improve.
