一、文字题及其与式题、应用题的联系和区别文字题是由数学名词(术语)、数字和问题三部分组成的,它是运用较简练的数学语言表达数量关系的数学题.式题是由数字(字母)、运算符号和结合符号组成的数学题.例如,6×(4+5)是由数字6、4、5,运算符号×、+,结合符号()组成的数学题.式题用数学语言进行文字叙述就变成了文字题,如上题可叙述为“6乘以4与5的和”.因此文字题是式题的语言(文字)表达形
First, the text and its problems with the type of problem, the problem and the difference between the application The problem is composed of math terms (terms), numbers and problems of three parts, it is the use of more concise mathematical language to express the quantitative relationship between mathematical problems. For example, 6 × (4 + 5) is a mathematical question consisting of the numbers 6, 4, 5, the operation signs ×, +, and the combination of signs () The expression of a mathematical expression in a mathematical language becomes a literal expression, which can be described as “6 times the sum of four and five.” Thus the literal expression is a linguistic (literal) expression of the formula
