用乘法分配律
3.74×3.6+0.374×4.4
=3.74×3.6+3.74×0.44
=3.74(3.6+0.44)
=3.74×4.04
=3.74(4+0.04)
=14.96+0.1496
=15.1096
3.74×3.6+0.374×4.4
=3.74×3.6+3.74×0.44
=3.74(3.6+0.44)
=3.74×4.04
=3.74(4+0.04)
=14.96+0.1496
=15.1096

3.74*3.6+0.374*4.4
=0.374*10*3.6+0.374*4.4
=0.374*(36+4.4)
=0.374*40.4
=15.1096
这是最简便的方法
