Knowledge expansion:

Oral arithmetic refers to the process of performing mathematical operations through mental arithmetic rather than paper, pen or other tools. This is a quick and simple calculation method, which plays an important role in children's mathematics learning and daily life.

First of all, oral calculation is a fast calculation method. By training and mastering oral arithmetic skills, children can complete a lot of mathematical operations in a short time, and improve the calculation speed and efficiency. For example, children can quickly answer the questions of addition, subtraction, multiplication and division through oral calculation without using paper and pencil or other tools.

Secondly, oral calculation is a simple calculation method. In our daily life, we often encounter some simple mathematical problems, such as calculating change when shopping, calculating time and date, etc. Through oral calculation, children can solve these problems quickly and accurately, and avoid wasting time and energy because of complicated calculation process.

In addition, oral calculation can also help children exercise their thinking ability and reaction ability. Oral calculation requires children to answer questions quickly and accurately, which requires children to have certain thinking ability and reaction ability. Through training and practice, children can gradually improve their thinking ability and reaction ability, so as to better cope with various mathematical problems and challenges.

Finally, verbal arithmetic is also an important mathematical skill. Mathematics is a basic subject, which plays an important role in children's future study and career development. By mastering language skills, children can better master the basic knowledge of mathematics and improve their mathematical literacy and comprehensive ability.
