11x11x11-11x11-10
=11x11x(11-1)-10
=11x11x10-10
=11x10x(10+1)-10
=11x10x10+11x10-10
=1100+110-10
=1100+100
=1200
36x1111+8888x8
=36x1111+1111x8x8

1式=11×11×(11-1)-10
=11×11×10-10
=10×(11×11-1)
=10×(121-1)
=1200
2式=36×1111+(1111×8×8)
=1111×(36+64)
=1111×100
=111100

11x11x11-11x11-10 =11x11x(11-1)-10 =11x11x10-10 =(11*11-1)*10=120*10=1200
36x1111+8888x8 =36*1111+1111*64=(36+64)*1111
=100*1111=111100
