Hello, the application questions have higher requirements for children's comprehensive ability:

1 first of all, children are required to be able to read the meaning of the question, and reading comprehension ability must be cultivated;

2. To understand the meaning of the question, you should also be able to combine the formula theorem, numbers and the meaning of the question to make a tabular answer;

3. In the process of solving, it is also required that the calculation is not wrong, which is also a test of children's computing ability.
