化简m-[n-2m-(m-n)]的结果化简m-[n-2m-(m-n)]的结果化简m-[n-2m-(m-n)]的结果m-[n-2m-(m-n)]=m-(n-2m-m+n)=m-(2n-3m)=m-2n+

化简m-[n-2m-(m-n)]的结果
化简m-[n-2m-(m-n)]的结果

化简m-[n-2m-(m-n)]的结果
m-[n-2m-(m-n)]
=m-(n-2m-m+n)
=m-(2n-3m)
=m-2n+3m
=4m-2n

5M-2N

4m-2n

m-[n-2m-m+n]
=m-2n+3m
=4m-2n

m-[n-2m-(m-n)]
=m-(n-2m-m+n)
=m-n+3m-n
=4m-2n

m-[n-2m-(m-n)]
=m-[n-2m-m+n]
=m-2n+3m
=4m-2n

m-[n-2m-(m-n)]
=m-[n-2m-m+n]
=m-2n+3m
=4m-2n

m-「n-2m-(m-n)」
=m-n+2m+m-n
=4m-2n
