32x102的简便方法计算
32x102用简便方法 -
32×102 =32×﹙100+2﹚
32×102 =32×(100+2)32×100+32×2 =3200+64 =3264
32×102 =32×﹙100+2﹚
32×102 =32×(100+2)32×100+32×2 =3200+64 =3264
32*(100+2)=3200+64=3264
如图,
教科书四年级下册数学书64页32x102简便运算该怎样算呢? -
这个问题我来答,如果有用请采纳。原式=32×(100+2)=32×100+32×2 =3200+64 =3264
104x24 =104x(20+4)=104x20+104x4 =2080+416 =2496 32x102 =32×(100+2)32×100+32×2 =3200+64 =3264
37×98+32×102简便计算怎么算? -
简便计算37×98+32×102 =5x98+32x98+32x102 =490+32x(98+102)490+32x200 =490+6400 =6890
32x102+42x86 =32x(100+2)42x(90-4)32x100+32x2+42x90-42x4 =3200+64+3780-168 =3264+3780-168 =7044-168 =6876 答题不易,望采纳!!
32x105和103x56和239x101和88X102最简便的计算方法? -
可以把这个数拆分,利用乘法的结合律进行简便运算。32*105 =32*(100+5)=32*100+32*5 =3200+160 =3360 103*56=(100+3)*56=100*56+3*56=5768 239*101=239*(100+1)=239*100+239=24139 88*102=88*(100+2)=88*100+88*2=8976 还有呢?
93x6+93x4 =93x(6+4)93x10 =930 32x11 =32x(10+1)32x10+32x1 =320+32 =352 78x102 =78x(100+2)78x100+78x2 =7800+156 =7956 36x9+36 =36x9+36x1 =36x(9+1)36x10 =360
