Question

a) 6+[5+(7+2)]=
b) 8+[4-(3+5)]=
c) 10-[6+(2+7)]=
d) 15-[10-(8+4)]=
f)12-[17-(2-10)]=
g) (-6)+[5+(2-12)]=
h) (-7)-[3-(4-9)]=​

Answer 1

Respuesta:

a) 6+[5+(7+2)]= 6 + [ 5 + (9)] = 6 + (14)= 20

b) 8+[4-(3+5)]= 8 + [4 - (8)] = 8 + (-4) = 4

c) 10-[6+(2+7)]= 10 - [ 6 + (9)] = 10 - 15 = -5

d) 15-[10-(8+4)]= 15 - [ 10 - (12)] = 15 - (-2) = 15 + 2= 17

f)12-[17-(2-10)]= 12 - [17 - (-8)] = 12 - [17 + 8] = 12 - 25 = - 13

g) (-6)+[5+(2-12)]= -6 + [5 +( -10)] = - 6 + (5 - 10)= -6 - 5 = -11

h) (-7)-[3-(4-9)]= -7 - [ 3 - (-5)] = -7 - (3 + 5)= - 7 - 8= -15

Espero sea de ayuda!
