4.2* 3.6+58* 0.36怎样简算...............
4.2* 3.6+58* 0.36怎样简算
...............
4.2* 3.6+58* 0.36怎样简算...............
4.2* 3.6+58* 0.36
=42*0.36+58*0.36
=0.36（42+58）
=36
42*0.36+58*0.36=0.36*(42+58)=36
4.2* 3.6+58* 0.36
=4.2*10*0.36+58*0.36
=42*0.36+58*0.36
=(42+58)*0.36
=100*0.36
=36
提取0.36
=0.36*(42+58)
=0.36*100
=36
4.2*3.6+58*0.36=4.2*3.6+5.8*3.6=(4.2+5.8)*3.6=36.完毕！
4.2* 3.6+58* 0.36
=4.2* 3.6+5.8* 3.6
=3.6(4.2+5.8)
=3.6×10
=36
