Answer 2

Resposta:

1) ( + 5 ) . ( + 3 ) = 15

2) ( + 4 ) . ( – 5 ) = -20

3) ( – 8 ) . ( + 4 ) = -32

4) ( – 6 ) . ( – 7 ) = 42

5) ( – 2 ) . ( + 4 ) . ( + 3 ) . ( – 1 ) = 24

6) ( – 5 ) . ( – 6 ) . ( – 2 ) = -60

7) 2 . (- 3 ) . ( + 6 ) = -36

8) (- 3 ) . 5 . ( – 7 ) = 105

9) (-8) . (-3) . 0 . (-15) = 0

10) 0 . ( -50) = 0

11) (-28) . ( -2 ). ( -1) = -56
