式题是由数字、运算符号和表示运算顺序的括号组成的题目;文字题是用数学语言来表达数量关系的题目;应用题是根据生产或日常生活中的实际问题,用语言、文字来表示数量关系的题目,其数量关系蕴含在情节中。三者的表现形式不同,但都是以反映数量关系这一主线而密切联系着的。如果用语言、文字叙述式题,式题就变成文字题;反过来,如果用数字、运算符号代替计算术语,文字题就变成了式题;如果用计算术语或运算符号来代替应用题的具体情节转化为数学问题并列式计算,则
The type question is a question composed of numbers, arithmetic symbols and parentheses indicating the order of operation. The word question expresses the question of quantity relationship in mathematical language. The question question is expressed in words and words according to practical problems in production or daily life The relationship between the number of issues, the number of relations contained in the plot. The three manifestations are different, but all are closely linked by reflecting the main line of quantitative relations. If the language, the text narrative type questions, style questions into the text problem; conversely, if the number of computing symbols instead of computing terms, text problems become a formula problem; if the calculation of terms or arithmetic symbols instead of application questions The specific plot into math problems parallel calculation, then
