Answer 1

Answers:

Sure, let's calculate the answers for each of the given problems:

1)
`\(7 + (-12) + (-3) = -8\)`

2)
`\(2 + 8 + 7 + (-6) = 11\)`

3)
`\(13 + 12 + 12 = 37\)`

4)
`\(6 - 18 + 16 + (-12) + 5 = -3\)`

5)
`\(24 + 19 + 5 + 3 = 51\)`

6)
`\(-24 + 2 = -22\)`

7)
`\(3.4 + 2.7 + 1.3 + (-1.2) = 6.2\)`

8)
`\(7 + 7 + 7 = 21\)`

9)
`\(-4 - 7 = -11\)`

10)
`\(2 + 5 = 7\)`

11)
`\(-2 + 6 = 4\)`

12)
`\(-2 + 1 = -1\)`

13 )
`\(-15 - 4 = -19\)`

14)
`\(7 - 19 = -12\)`

15)
`\(5 + 20 = 25\)`

16)
`\(-24 + 2 = -22\)`

17)
`\(-2 + (-7) - 1 = -10\)`

18)
`\(7 + 13 - 12 = 8\)`

19)
`\(-15 + 3 - 8 = -20\)`

20)
`\(-1 - 13 + (-17) = -31\)`

21)
`\(-3 + 7 + 18 = 22\)`

22)
`\(14 + 3 - 4 + 1 = 14\)`

23)
`\(27 - 3 + (-24) = 0\)`

24)
`\((14 + 6) - (-5 - 13) = 38\)`

25)
`\(10 - (5 + (-7) + 2) = 14\)`

26)
`\((-3 + 10) - ((5 - 8) + (-10)) = 10\)`

27)
`\((-4 + 2) + (-16 - 5) = -23\)`

28)
`\((27 + 6) + (-6) = 27\)`

29)
`\(27 - (-6 + (-6)) = 39\)`

30)
`\((16 - 4) - (8 + 12) = -8\)`

Now, connecting the answers in order:

-8, 11, 37, -3, 51, -22, 6.2, 21, -11, 7, 4, -1, -19, -12, 25, -22, -10, 8, -20, -31, 22, 14, 0, 38, 14, 10, -23, 27, 39, -8.
