= 1125-374-1125+(-65)+374
= (1125-1125)-(374-374)+(-65)
= 0-0+(-65)
= (-65)
=1125 - 1499 + 309
=-374 + 309
=-65
tick cho mình nhé
1125 - ( 374 + 1125)+ ( -65 + 374)
= 1125 - 374 -1125 + -65 + 374
= (1125-1125)-374+ -65 + 374
= 0 -374 + 374 + -65
= 0 + - 65 = -65
1125 - ( 374 + 1125 ) + ( -65 +374 ) = 1125 - 1499 + 309
= -374 +309 = - 65
1125 - (374 + 1125 ) + (-65 + 374)
=1125 - 1499 + 309
= -374 + 309
= -65
