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

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!
