3.05-0.56+2.95-0.44能否用简便计算
3.05-0.56+2.95-0.44能否用简便计算
3.05-0.56+2.95-0.44能否用简便计算
3.05-0.56+2.95-0.44
=3.05+2.95-(0.56+0.44)
=6-1
=5
3.05-0.56+2.95-0.44
=(3.05+2.95)-(0.56+0.44)
=6-1
=5
不懂再问哦
能
3.05+2.95-0.56-0.44=6-1=5
结合律
3.05+2.95-(0.56+0.44)
6-1
5
3.05-0.56+2.95-0.44
=(3.05+2.95)-(0.56+0.44)
=6-1
=5
能啊:3.05+2.95-(0.56+0.44)
结果就等于5啦!
=3.05+2.95-0.56-0.44
=6-1
=5
哦了,这是脱式计算哦,↖(^ω^)↗努力学习,不懂的再问哦~
