估算,是指不作精确的计算,只大略估算一个数学问题范围的计算方法。有同学可能认为数学是一门严谨的科学,在思考数学问题的时候,应当精确地计算出问题的答案,而不应当只是粗略地估算答案。估出一个不精确的答案有什么作用呢?实际上,估算是一个帮助同学们解决数学问题的好技巧。一、运用估算方法检验答案同学们在做完数学习题以后,有时想知 Estimation refers to the calculation method that does not make accurate calculations and only roughly estimates the scope of a mathematical problem. Some students may think that mathematics is a rigorous science. When thinking about mathematical problems, the answers to the questions should be precisely calculated, rather than simply estimating the answers. What is the effect of estimating an inaccurate answer? In fact, estimation is a good trick to help students solve math problems. First, the use of estimation methods to test the answer Students after completing the number of learning problems, and sometimes want to know
