Math fill in blank is one of the three types of questions in the mathematics examinations, which is an objective question. To ensure an accurate, reasonable, and prompt answer to the blank-filling question, it should meet the following basic requirements. 1 Careful examination of questions is the premise of answering the blank-filling question.
