# Senior One # Introduction Mathematics is a basic science, which is worth learning by everyone, especially children. Learning mathematics is to build their own thinking system. Learning mathematics means learning a thinking system, and we should also pay attention to this in the process of teaching children every day. The following is the related information of "Three Math Calculation Problems in the First Grade of Primary School" compiled by KaoNet. I hope it will help you.
