Experts in computing are better, because experts in computing can further analyze and test the knowledge in textbooks. Homework in class can be understood as basic knowledge, and experts in computing mainly strengthen and consolidate. Class assignments and textbooks are basically synchronized; The design of a mathematical calculation expert embodies the idea of practicing every day and consolidates the practice on the basis of book knowledge. So it would be better to be an expert in calculation.

Experts in calculation cover every day of the semester, including oral calculation and estimation from Monday to Friday, and written calculation training corresponding to this learning stage is arranged on Saturday and Sunday. Thus, a more scientific and complete computing ability training system is formed.
