A) a= (-2022)-(111-2022)

B) b=(-8).(-2).(-5).6

2 câu trả lời

$a)A=(-2022)-(111-2022)$

$A=(-2022)-111+2022$

$A=[(-2022)+2022]-111$

$A=0-111$

$A=-111$

$b)B=(-8).(-2).(-5).6$

$B=16.(-30)$

$B=-480$

a) A = (-2022) - (111 - 2022)
    A = (-2022) - 111 + 2022

    A = [(-2022) + 2022] - 111
    A = 0 -111
    A = -111
b) B = (-8).(-2).(-5).6
    B = [(-2).(-5)].[(-8).6]
    B = 10 . -48
    B = -480
