Answer 1

Respuesta:

Explicación paso a paso:

(+7) - (-5) - (+2) + (-6) =

7 - -5 - 2 + -6 =

12 - -4 = 16

-(-9) - (+7) + (-8) + (+6) =

9 - 7 + -8 + 6 =

2 + -2 = 0

(-1) - (+15) - (-13) + (+7) =

-1 - 15 - -13 + 7 =

-16 - -6 = -10

- (+2) + (-5) - (-17) - (+8) - (+4) =

-2 + -5 - -17 - 8 - 4 =

-7 - -25 - 4 =

18 - 4 = 14

3 + (-2) • (+7) =

3 + -2 • 7 =

1 • 7 = 7

-4 + (-11) : (+11) =

-4 + -11 : 11 =

-15 : 11 = -1,36

5 + (+2) • (+9 - 4) =

5 + 2 • 5 =

7 • 5 = 35
