4+{ [-7+(3+2)-(2) ]+[ (-3)-(+8-8)+(-10) ] } + 10-3=

Answer 1

Respuesta:

-5+(-6)-(-5)-(-9)-(7)+(-10)+7-12

-5-6+5+9-7-10+7-12=-19

(-6+(4+2)-(-9))-((-4)-(7-5)+(-12))+7-15

(-6+6+9)-(-4-2-12)-8

9-(-18)-8

9+18-8=19

4+((-7+(3+2)-(2))+((-3)-(8-8)+(-10))+10-3

4+(-7+5-2)+(-3-10)+7

4+(-4)+(-13)+7

-13+7=-6
