Question

a). (-5) (4) (-1)=
b). -8(6-7) =
c). (-75÷15 =
d). 40 ÷ (13 + 10) =
e). -7(3 + 5) =
f). (-6) (-5) (-4) (-3) (-2) =​

Answer 1

a.

$( - 5) \times ( 4) \times ( - 1) \\ - 20 \times ( - 1) = 20$

b.

$- 8 \times (6 - 7) \\ - 8 \times ( - 1) = 8$

c.

$( - 75) \div 15 = - 5$

d. (resultado aproximado)

$40 \div (13 + 10) \\ 40 \div 23 = 1.74$

e.

$- 7 \times (3 + 5) \\ - 7 \times 8 = 56$

f.

$( -6) \times ( - 5) \times ( - 4) \times ( - 3) \times ( - 2) \\ 30 \times ( - 4) \times ( - 3) \times ( - 2) \\ - 120 \times ( - 3) \times ( - 2) \\ 360 \times ( - 2) = - 720$
