Answer 2

1) –34 + 67 + (–19) + (–44) + 34 = –34 + 34 + 67 – 44 – 19 = 0 + 67 – 44 – 19 = 67 – 44 – 19 = 23 – 19 = 4 2) 6 + (–7) – (–15) – (–6) – 30 = 6 – 7 + 15 + 6 – 30 = –1 + 15 + 6 – 30 = 14 + 6 – 30 = 20 – 30 = –10 3) –42 + 54 + (–13) + (–26) + 32 = –42 + 54 + 32 – 13 – 26 = 12 + 32 – 13 – 26 = 44 – 13 – 26 = 31 – 26 = 5 4) 8 + (–13) – (–11) – (–7) – 42 = 8 – 13 + 11 + 7 – 42 = –5 + 11 + 7 – 42 = 6 + 7 – 42 = 13 – 42 = –29
