Answer 1

Explicación paso a paso:

a) +5-2-6= +5 - 8 = -3

b) 4-8+13-6= 17 - 14 = 3

c) +12-6-7-9+3= 15 - 22 = - 7

d) -12-15+6+9+12= 27 - 27 = 0

e) (+6-15+3-9) - (-3-5+11-10+9) = (- 15) - (2) = - 13

f) (-12+9) + (-16+20) - (+13-6-15) = (-3) + (4) - (-8) = 9

Answer 2

Respuesta:

a) +5-2-6= -3

b) 4-8+13-6= 3

c) +12-6-7-9+3= -7

d) -12-15+6+9+12= 0

e) (+6-15+3-9) - (-3-5+11-10+9) = (-15) - (+2) = -15 -2 = -17

f) (-12+9) + (-16+20) - (+13-6-15) = (-3) + (+4) - (-8) = -3 + 4 + 8 = 9
