When calculating, we should fully understand the representation of numbers in different decimal systems and the representation of numbers, so as to calculate numbers correctly.

The function of counting

Promoting children's counting ability and mathematical thinking ability: Only by deeply understanding what counting is and what counting should be emphasized in learning will it be of great help to promote children's counting ability and mathematical thinking ability. Exercise children's computing ability: By counting, children's computing ability can be exercised by radix method.

Help children to establish mathematical thinking: Counting is an abstract process, and it is a method to train children's ability and cultivate their abstract logical thinking. Help children establish the concept of numbers: by counting, let children have a clearer understanding and understanding of numbers.
