0.88×98+4.4×0.4 简便运算

0.88×98+4.4×0.4 简便运算
0.88×98+4.4×0.4 =0.88×98+0.44×4
= 0.88×98+0.88×2
=0.88×(98+2)
=0.88×100
=88

0.88×98+4.4×0.4
=8.8x9.8+4.4x0.4
=4.4x19.6+4.4x0.4
=(19.6+0.4)x4.4
=20x4.4
=88

0.88×98+4.4×0.4
=0.88×98+0.88×2
=0.88×(98+2)
=0.88×100
=88

=0.88*(100-2)+0.44*4=0.88*100-0.88*2+0.88*2=88
