估算,是一种重要的数学思想方法和数学能力。在日常生活中,处处有计算,也处处离不开估算。一个人在一天活动中估计和差积商的次数,远比进行精确计算的次数要多得多。所以说,估算能力的强弱直接影响到了人们生活节奏的快慢和学习、工作效率的高低。随着计算工具的飞速发
Estimation is an important mathematical method and mathematical ability. In everyday life, there are calculations everywhere and can not do without estimates. The number of times one person estimates and differential integrators in a day’s activity is far greater than the number of exact calculations. So, the strength of estimation ability has a direct impact on the pace of people’s life and the level of learning and work efficiency. With the rapid development of computing tools
