a - ( +15 ) • ( -20 ) =
b - ( - 18 ) • ( - 18 ) =
c - ( -26 ) • ( +14 ) =
d - ( +32 ) • ( -11 ) =

e - ( -4 ) • 3 • ( -5 ) • 0 =
f - 6 • ( -1 ) ( -1 ) ( -1 ) • 2 =
g - -1 • ( -4 ) • 3 • ( -3 ) • 2 =
h - ( -2 ) • 3 • ( -5 ) • ( -1 ) • ( - 10 ) =

​

Answer 1

a)

$( + 15) \times ( - 20) = - 300$

b)

$( - 18) \times ( - 18) = 324$

c)

$( - 26) \times ( + 14) = - 364$

d)

$( + 32) \times ( - 11) = - 352$

e)

$( - 4) \times 3 \times ( - 5) \times 0 = 0$

f)

$6 \times ( - 1) \times ( - 1) \times ( - 1) \times 2 = - 12$

g)

$- 1 \times ( - 4) \times 3 \times ( - 3) \times 2 = - 72$

h)

$( - 2) \times 3 \times ( - 5) \times ( - 1) \times ( - 10) = + 300$

Answer 2

Resposta:

a) -300; b) +324; c) -364; d) -352; e) 0; f) -12; g) -72; h) +300.

a) (+15) . (-20) =

- 300.

b) (-18) . (-18) =

324.

c) (-26) . (+14) =

- 364

d) (+32) . (-11) =

- 352.

e) (-4) . 3 . (-5) . 0 =

-12 . (-15) . 0 =

180 . 0 =

0.

f) 6 . (-1) . (-1) . (-1) . 2 =

- 6 . 1 . 2 =

- 6 . 2 =

- 12.

g) (-1) . (-4) . 3 . (-3) . 2 =

4 . (-9) . 2 =

- 36 . 2 =

- 72.

h) (-2) . 3 . (-5) . (-1) . (-10) =

- 6 . 5 . (-10) =

- 30 . (-10) =

300.
