-418-{-418-[-418-(-418+2003)]}
-418 - { -418 - [ -418 - ( -418 + 2003 ) ] }
= -418 - [ -418 - ( -418 + 418 - 2003 ) ]
= -418 - [ -418 - ( -2003 ) ]
= -418 - ( -418 + 2003 )
= -418 + 418 - 2003
= 0 - 2003
= -2003.
-418-{-418-[-418-(-418+2003)]}=-418+418+[-418-(-418+2003)]=-418-(-418+2003)=-418+418-2003=-2003

b, -418 - {- 418 - [ -418 - (-418) + 2021]}
= -481 - { -418 - [ 0 + 2021]}
= -481 + 418 + 2021
= 2021
d, 23 - 501 - 343 + 61 - 257 + 16 - 499
= (23 + 61 + 16) - (501 + 499) - (343 + 257)
= 100 - 1000 - 600
= 100 - 1600
= -1500
e, 743 - 231 + (-495) - (-69) - 38 + (-117)
= 512 - 426 - 155
= 86 - 155
= - 69

b/-418-{-418-[-418-(-418+2003)]}
c/-1+2+3-4-5+6+7-8-…+99-100-101
Tính nhanh
a) (326-43)+(174-57)
b) (351-875)-(125-149)
c) -418-{-418-[-418-(-418+2016)]}

A=(15-17)-|-3|-[(-2).3-(-3)mũ 2]
B=418+{418-(418+2018)]}
C=(12/199+23/200-34/201).(1/2-1/3-1/6)
A = (15-17) - |-3| - [ (-2).3 - (-3)2 ]
A = (-2) - 3 - [ (-6) - 9 ]
A = (-5) - (-15)
A = (-5) + 15
A = 10
B = 418 + [ 418 - (418+2018) ]
B = 418 + [ 418 - 2436 ]
B = 418 + (-2018)
B = -1600
Chúc bạn học tốt!
