二年级数学下册计算题?解析:先算乘法4 × 9 = 36,再算加法36 + 36 = 72(注意这里的36是题目中给出的数,不是上一步的结果与这一步的乘法结果相加,而是分别计算后再相加),最后算减法72 - 18 = 54。但更严谨的写法应该是分步写出每一步的结果,那么,二年级数学下册计算题?一起来了解一下吧。

小学二年级数学脱式计算题解析与练习
脱式计算是小学数学中的重要部分,它要求学生能够按照运算的优先级(先乘除后加减,有括号先算括号里的)进行分步计算,并得出最终结果。通过脱式计算,学生可以更好地理解数学运算的规律和逻辑,从而提高数学成绩。
以下是一些适合小学二年级学生的脱式计算题,以及详细的解析和答案:
例题1:125 - 25 × 5 + 75= 125 - 125 + 75 (先算乘法)= 0 + 75 (再算减法)= 75 (最后算加法)
例题2:(80 - 14) ÷ 6 + 9= 66 ÷ 6 + 9 (先算括号里的减法)= 11 + 9 (再算除法)= 20 (最后算加法)
例题3:3 × (15 - 7) ÷ 2= 3 × 8 ÷ 2 (先算括号里的减法)= 24 ÷ 2 (再算乘法)= 12 (最后算除法)
练习题:
72 ÷ 9 - 4 + 5
解析:先算除法72 ÷ 9 = 8,再算减法8 - 4 = 4,最后算加法4 + 5 = 9。
