=37*(176-56+120)
=37*240
=8880
37 x 176 - 37 x 56 + 120 x 73
= 37 x ( 176 - 56 ) + 120 x 73
= 37 x 120 + 120 x 73
= 120 x ( 37 + 73 )
= 120 x 110
13 200
^^ Cbht!!!
37 x 176 - 37 x 56 + 120 x 73
= 37 x ( 176 - 56 - 120 ) + 73
= 37 x 0 + 73
= 0 + 73
= 73
=37nhan(167-56) +120 nhan73 = 37nhan 120 + 120 nhan 73 = 120 nhan ( 37 +73) = 120nhan 100=12000
37*176-37*56+120*73=37*(176-56)+120*73=37*120+120*73=120*(73+37)=120*100=12000
