需要每步的过程

数学题简便算法,急需答案999*222+333*334需要每步的过程
999x222+333x334
=333x3x222+333x334
=333x666+333x334
=333x(666+334)
=333x1000
=333000

999*222+333*334
=333*3*222+333*334
=333(666+334)
=333*1000
=333000

原式=333*3*222+333*334
=333*(666+334)
=333000

(9*2+3*3)*111*111+333
=2997*111+3*111=3000*111=333000

=999*222+333*(333+1)
=999*222+333^2+333
=111*9*111*2+111*3*111*3+111*3
=18*111^2+9*111^2+111*3
=27*111^2+111*3
=333*(999+1)
=333*1000
=333000

999x222+333x334
=333x3x222+333x334
=333x666+333x334
=333x(666+334)
=333x1000
=333000
