Answer 1

Respuesta:

Explicación paso a paso:

a) (–3) · [(–2) + (– 4)] = -18

b) (+4) · [(–5) + (+2)] = -12

c) (+6): [(+5) – (+7)] = -3

d) (–20): [(–6) – (–2)] =  5

e) [(–8) + (+7)] · (–3) = 3

f) [(–9) + (–3)]: (+6) = -2

g) 19 – (–3) · [5 – (+8)] = 10

h) 12 + (–5) · [8 + (–9)] = 17

i) 12 – [13 – (–7)]: (–5) = 16

j) 10 – (+20): [7 + (–3)] = 5

k) (–2) · (5 – 7) – (–3) · (8 – 6) = 4 - 6=-2

l) (9 – 6) · (–2) + (13 + 3) : (–4) = -6 -4=-10
