题目内容
口算下面各题: 3×3= |
8×6= | 5×7= | 88+8= |
3×6= | 8×7= | 6×5= | 67-40= |
8+37= | 48-7= | 32-8= | 40+28= |
8×2= | 4×9= | 41-2= | 5×8+20= |
38-18+25= | 6×4-10= |
分析:5×8+20先算乘法,再算加法;38-18+25先算减法,再算加法;6×4-10先算乘法,再算减法;其它题目根据运算法则直接求解.
解答:解:
故答案为:9,48,35,96,18,56,30,27,45,41,24,68,16,36,39,60,45,14.
3×3=9, | 8×6=48, | 5×7=35, | 88+8=96, |
3×6=18, | 8×7=56, | 6×5=30, | 67-40=27, |
8+37=45, | 48-7=41, | 32-8=24, | 40+28=68, |
8×2=16, | 4×9=36, | 41-2=39, | 5×8+20=60, |
38-18+25=45, | 6×4-10=14. |
点评:本题考查了基本的计算,计算时要细心,注意运算的顺序.
