  1. Giải đáp:
    1)
    152-274-(-248)+(-26)
    =152-274+248+(-26)
    =(152+248)+(-274-26)
    =400-300
    =100
    2)
    (87-37):(-5)+(19-26).(-3)^2
    =50:(-5)+(-7).9
    =-10-63
    =-73

  2. @Mem gửi bạn
    Xin hay nhất
    152 – 274 – ( -248 ) + ( -26 )
    = 152 – 274 + 248 – 26
    = ( – 122 ) + 248 – 26
    = 126 – 26
    = 100
    ( 87 – 37 ) : ( -5 ) + ( 19 – 26 ).$(-3)^{2}$
    = 50 : ( -5 ) + ( – 7 ) . 9
    = ( – 10 ) + ( -63 )
    = – 73
