Answer 1

Respuesta:

42) 3 + 2 + (4 – 3 –2) =  4

43) –5 – 1 + (5 – 6 – 7) =  -14

44) –3 + (– 1 – 3 + 5) – 2 =  -4

45) –7 + (–3 + 4 – 5 – 8) =  -19

46) 5 – 3 + (–8 – 1 + 5) – 3 =  -5

47) –2 – 3 – (–8 – 1 + 4) =  -10

48) 5 – (–4 + 3 – 8) – 4 =  -8

49) 3 – 2 – (–4 + 5 – 8) =  -6

50) –3 – 7 – (9 – 8 – 5) – 3 =  -17

51) 3 + (–2 + 5 – 7) – (–4 + 7 – 2) =  0

52) 2 – 3 – (4 – 7– 1) + (–2 – 3) =  -10

53) 1 – 5 + (–3 – 2 – 1) – (–5 + 7 – 3) = -11
