    a) (-37) + (-112) = – 149
    b) -42 + 52 = (-42) + 52 = 10
    c) 13 – 31 = -18
    d) 14 – 24 – 12 = (-10) – 12 = -22
    e) ( -25) + 30 -15 = 5 – 15 = -10

    a)
    $(–37 ) + (–112)$
    $= –(37 + 112)$
    $= –149$
    b)
    $(–42) + 52$
    $= 52 – 42$
    $= 10$
    c)
    $13 – 31$
    $= –31 + 13$
    $= – (31 – 13)$
    $= –18$
    d)
    $14 – 24 – 12$
    $= 14 – (24 + 12)$
    $= 14 – 36$
    $= – (36 – 14)$
    $= –22$
    $#A$
    $#Xin hay nhất$
