125乘以7乘以88简便计算是怎么算的

125*7*88=125*8*11*7=77000

125*7*88
=125*8*7*11
=77000

88=8*11
125*8=1000
1000*7*11=77000

125x7x88=125x8x7x11=1000x77=77000

125*7*88
=125*7*(80+8)
=(10000+1000)*7
=11000*7
=77000

125*7*(8*11)
=(125*8)*(7*11)
=1000*77
=77000

125*7*88
=125*7*8*11
=125*8*7*11
=1000*77
=77000

125x7x88=(125x8)x(11x7)=1000x77=77000
