Answer 1

Respuesta:

1-. -18

2-. 10

3-. -9

4-. -2

Explicación paso a paso:

-10+[-(-3+5+6)+(+12-17+5)]

-10+[-(+2+6)+(-5+5)

-10+[-8 + 0]

-10 -8

-18

--------------------------------------------------------------------

+8-[-(10+2-3)+(-10-2-15)]

+8-[-(+12-3)+(-12-15)]

+8-[-9 + 27]

+8 - 18

10

--------------------------------------------------------------------

+10{+[-(-20+2+3)-(-3-2+5)]-10+12}

+10 {+ [-(18 +3) - (-5 + 5)] -10 + 12}

+10 {+[-21 - 0] -10 + 12}

+10 {- 21 - 10 +12}

+10 {-31 +12}

+10 -19

-9

----------------------------------------------------------------------

+2-[+(-2+10-3)+(-2+7-9)+3]​

+2-[+(+8-3) + (+5-9) +3]

+2-[+5 -4 +3]

+2- [+1 +3]

+2 -4

-2
