88888*22222+33333*7408,简便运算

88888*22222+33333*7408
= 88888*22222+3*11111*2*3704
= 88888*22222 + 22222*11112
= 22222*(88888 + 11112)
= 22222*100000
= 2222200000

88888*22222+33333*7408
=8*2*11111*11111+3*11111*7408
=16*11111*11111+11111*22224
=16*11111*11111+11111*(22222+2)
=16*11111*11111+11111*2*11111*+2*11111
=18*11111*11111+2*11111
=11111*11111*(10+8)+2*11111
=11111*11111*10+8*11111*11111+2*11111
=11111*111110+11111*(88888+2)
=11111*111110+11111*88890
=11111*(111110+88890)
=11111*200000
=2222200000

88888×22222+33333×7408=88888×22222+33333÷1.5×1.5×7408=88888×22222+(33333÷1.5)×(1.5×7408)=88888×22222+22222×11112=22222×(88888+11112)=22222×100000=2222200000

88888*22222+33333*7408
=11111*(88888*2+3*7408)
=11111*(177776+22224)
=11111*200000
=2222200000
