Question

a) 5 – (9 – 3) = 5 – 9 + 3 = 8 - 9 = -1 5 – (+6) = 5 – 6 = -1
b) 7 + (2 – 8) =
c) 12 + (–3 + 10) =
d) 15 – (8 + 11) =
e) +(9 – 10) – 2 =
f) –(7 + 4) + 14 =
g) (5 + 8) – (7 + 6) =
h) (16 – 9) – (10 – 7) =

Answer 1

b) 7+(2-8)=7+(6)=7+6=13

c)12+(-3+10)=12+(-13)=12+-13= -25

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

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

f) -(7+4)+14= -(11)+14= -11+14=-25

g) (5+8)-(7+6)=(10)-(13)=10-13=-3

h)(16-9)-(10-7)=(7)-(3)=7-3=4

Answer 2

Respuesta:

b) 7+(2-8)=7+(6)=7+6=13

c)12+(-3+10)=12+(-13)=12+-13= -25

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

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

f) -(7+4)+14= -(11)+14= -11+14=-25

g) (5+8)-(7+6)=(10)-(13)=10-13=-3

h)(16-9)-(10-7)=(7)-(3)=7-3=4
