Explicación paso a paso:
a. [(+6) ∙ (– 4)] : (–3) b. [(–15) ∙ (–2)] : (+6) c. (–5) ∙ [(+12) : (–3)]
(-24) : (-3) 15 . 2 (-5) . (-4)
24 : 3 30 20
8
d. [(–5) ∙ (+12)] : (–3) e. 5 ∙ (– 4) + 2 ∙ (–3) f. 20 : (–5) – 8 : (+2)
(-60) : (-3) -20-6 -4-8 : 2
20 -26 -4 -4
-8
g. 2 ∙ (–8) – 3 ∙ (–7) – 4 ∙ (+3) h. 6 : (+2) + 5 ∙ (–3) – 12 : (–4)
- 16 +21 -12 3 -15 +3
