100.1x3.6+9.9x3.4
=(100+0.1)x3.6+(10-0.1)x3.4
=100x3.6+0.1x3.6+10x3.4-0.1x3.4
=100x3.6+10x3.4+0.1x3.6-0.1x3.4
=360+34+0.1x(3.6-3.4)
=394+0.1x0.2
=394+0.02
=394.02
=(100+0.1)x3.6+(10-0.1)x3.4
=100x3.6+0.1x3.6+10x3.4-0.1x3.4
=100x3.6+10x3.4+0.1x3.6-0.1x3.4
=360+34+0.1x(3.6-3.4)
=394+0.1x0.2
=394+0.02
=394.02

(100+0.1)*3.6+(10-0.1)*3.4
=360+0.36+34-0.34
=394+0.02
=394.02
=360+0.36+34-0.34
=394+0.02
=394.02

100.1x3.6+9.9x3.4
=100*3.6+0.1*3.6+10*3.4-0.1*3.4
=360+0.36+34-0.34
=394.02
=100*3.6+0.1*3.6+10*3.4-0.1*3.4
=360+0.36+34-0.34
=394.02

简便计算如下：
100.1x3.6+9.9x3.4
=(100+0.1)x3.6+(10-0.1)x3.4
=100x3.6+0.1x3.6+10x3.4-0.1x3.4
=100x3.6+10x3.4+0.1x3.6-0.1x3.4
=360+34+0.1x(3.6-3.4)
=394+0.1x0.2
=394+0.02
=394.02
100.1x3.6+9.9x3.4
=(100+0.1)x3.6+(10-0.1)x3.4
=100x3.6+0.1x3.6+10x3.4-0.1x3.4
=100x3.6+10x3.4+0.1x3.6-0.1x3.4
=360+34+0.1x(3.6-3.4)
=394+0.1x0.2
=394+0.02
=394.02
