4.4x5.5-44x0.33-0.44x22这道题怎么做

=44*(0.55-0.33-0.22)=0

=4.4x5.5-44/10x0.33x10-0.44x10x22/10
=4.4x5.5-4.4x3.3-4.4x2.2
=（5.5-3.3-2.2）x4.4
=0x4.4
=0

4.4x5.5-44x0.33-0.44x22
=4.4x5.5-4.4x3.3-4.4x2.2
=4.4x(5.5-3.3-2.2)结合
=4.4x0
=0

好了

0.1x44x5.5-44x0.33-0.01x44x22=44(0.1x5.5-0.33-0.01x22）=44x（0.55-0.33-0.22）=44x0=0

全部换成4.4乘以某数
原式=4.4x(5.5-3.3-2.2) 我快了一步
=0

4.4*5.5-44*0.33-0.44*22
=4.4*5.5-4.4*3.3-4.4*2.2
=4.4*(5.5-3.3-2.2)
=4.4*0
=0
