Question

me ayudan porfavor :)

Answer 1

Respuesta:

(-4)-(+7)= -4-7 = -11

-(-8)+(-2)= +8-2 = 6

(-2)+(-3)-(+5)= -2-3-5 = -10

12+(-9)-(+8)-(-3)= 12-9-8+3 = -2

(-9)-(-8)+(-7)-6= -9+8-7-6 = -14

(-5)-[25+(-4)]= -5-[25-4]= -5-21 = -26

(-2)-(-4+5)+3= -2-(1)+3 = -2-1+3= 0

2-[(-9--2)+(-4)]-2= 2-[(-9+2)-4]= 2-[-7-4] = 2-[-11]=2+11 = 13
