A good oral calculation is the basis of correct calculation, a necessary condition to improve teaching effect and a good way to develop students' intelligence. Schools and parents should attach importance to students' education in this respect, rather than just writing compositions and doing problems. The following is the relevant information of "A Complete Collection of Mathematical Addition and Subtraction Problems in the First Grade of Primary School", hoping to help you.
