Explicación paso a paso:

1)

(-2) - (+7) - (-12) + (+5)

(-2) -7 - (-12) + (+5)

(-2) -7 + 12 + (+5)

(-2) -7 + 12 + 5

-9 + 12 + 5

3 + 5

8

2)

-10 - (+2) + (-5) + (+4) - (-20)

-10 - 2 + (-5) + (+4) - (-20)

-10 - 2 - 5 + (+4) - (-20)

-10 - 2 - 5 + 4 - (-20)

-10 - 2 - 5 + 4 + 20

-12 - 5 + 4 + 20

-17 + 4 + 20

-13 + 20

7

3)

+15 - (-15) - (+15) + (-15)

+15 + 15 - (+15) + (-15)

+15 + 15 - 15 + (-15)

+15 + 15 - 15 -15

30 - 15 -15

15 -15

0

4)

(-2) • (+7) • (-12) • (+5)

(-14) • (-12) • (+5)

168 • (+5)

840

5)

-10 • (+2) • (-5) • (+4) • (-20)

-20 • (-5) • (+4) • (-20)

100 • (+4) • (-20)

400 • (-20)

-8000

6)

( +15 - (-15) ) • (+15) + (-15)

( 15 + 15 ) • (+15) + (-15)

30 • (+15) + (-15)

30 • (+15) - 15

450 - 15

435

8)

(-1) ^20

1

9)

(-1)^ 33

-1

10)

(-3)^5 • (+2)^4 • ( (-4)^2 + (-2) )

(-3)^5 • (+2)^4 • ( (-4)^2 -2 )

(-3)^5 • (+2)^4 • ( 16 -2 )

(-3)^5 • (+2)^4 • 14

-243 • (+2)^4 • 14

-243 • 16 • 14

-243 • 16 • 14

-3888 • 14
