f) –(7 + 4) + 14 =

g) (5 + 8) – (7 + 6) =

Answer 1

Respuesta:

b) 7 + (2 – 8) =  7 + (-6) = 7 - 6 = 1

c) 12 + (–3 + 10) =  12 + (+7) = 12 + 7 = 19

d) 15 – (8 + 11) =  15 - (+19) = 15 - 19 = -4

e) +(9 – 10) – 2 =  +(-1) -2 = -1 -2 = -3

f) –(7 + 4) + 14 =  -(+11) + 14 = -11 +14 = +3

g) (5 + 8) – (7 + 6) = (+13) - (+13) = 13 - 13 = 0

Answer 2

b)7+(2-8)=7+(-6)=7-6=1

c)12+(-3+10)=12+(7)=19

d)15-(8+11)=15-(19)=-4

e)+(9-10)-2=+(-1)-2=-3

f)-(7+4)+14=-(11)+14=-11+14=3

g)(5+8)-(7+6)=13-13=0
