数学是科学的皇后,也是美的化身,数学题不完全是考查知识能力的试金石,同时也是体现数学美的载体。由此可见,学生必须从小学好数学这门学科,为其它学科做坚固的后盾。因此,学生就必须以最简单、最基础的数的运算开始着手。数的运算是小学数学教学中比较重要的一个环节,也是需要学生熟练掌握,灵活运用的一项基本技能。 Mathematics is the Queen of Science, but also the embodiment of the United States. Mathematics is not the touchstone of test of knowledge ability, but also the carrier of the beauty of mathematics. From this we can see that students must be good at mathematics in elementary school so as to provide a strong backing for other disciplines. Therefore, students must begin with the simplest, most basic arithmetic. The number of operations is an important part of primary mathematics teaching, but also requires students to master and apply a basic skills.
