Answer 1

Explicación paso a paso:

Recordemos que al multiplicar signo lo siguiente

(+).(+)+

(-). (-)= +

(+).(-)= -

•Resolvemos

1. – ( - ) = +

2. – (+)(-) =

-(-)= +

3. +(-) = -

4. +(+)(-) = -

5. –(+)(-)(-)(+) =

-(-)(-)= -

6. – (11) = -11

7. – (- 13) = 13

8. – (- 40) = 40

9. - 2(4) = -8

10. - 5(- 3) = 15

11. 3(- 8) = -24

12. – 8 + (- 10) = -18

13. – 5 + (- 6) = -11

14. - 3.4 + (- 5.6) =

-12 -30 = -42

15. - 8.4 + (+ 3.6) =

-32. + 18 = -14
