1152-(374+1152)+(374-65)
=1152-374-1152+374-65(theo quy tắc đổi dấu)
=(1152-1152)+(-374+374)-65
=0+0-65
=-65
1152-374-1152+374-65 =(1152-1152) +(-374+374)-65=0+0-65= 0-65= -65
1152-[374+1152]+[374-65]=[374+(1152-1152)]+(374-65)=374+(374-65)=683
1152-[374+1152]+[374-65]
1152-374-1152+374-65
1152-1152-374+374-65=-65
1152 - (374 + 1152) + (374 - 65)
= 1152 - 374 - 1152 + 374 - 65
= (1152 - 1152) - (374 - 374) - 65
= 0 - 0 - 65
= 0 - 65
= -65
