Answer 2

Calculation:

Let's calculate the given expressions step by step:

1) -1 + 4 + 3 + 5 - The sum of -1, 4, 3, and 5 is 11.

2) 9 + 11 - (2 + 5) - 3 - 20 + 21 + 3 + 7 - The sum of 9, 11, - (2 + 5), - 3, - 20, 21, 3, and 7 is 23.

3) -8 + 9 + 14 + 3 + 3 + 7 - The sum of -8, 9, 14, 3, 3, and 7 is 28.

4) 7 + 5 + 12 - (-3 + 7 + 24) - The sum of 7, 5, 12, and - (-3 + 7 + 24) is 38.

5) 6 - 6 + 11 + 12 - (-8 + 13 + 18) + 7 - The sum of 6, -6, 11, 12, - (-8 + 13 + 18), and 7 is 59.

6) 5 + 12 - (10 + 8) - 11 + 7 + 9 + 8 + 2 + 15 - The sum of 5, 12, - (10 + 8), - 11, 7, 9, 8, 2, and 15 is 49.

7) -3 + 1 + 12 + 1 + 6 + 1193 + 6 + 7 - (-6 + 4 + 9) + 119 + 1 + 6 - (-5 + 3 + 4) + 12 - 3 + 8/9 - (-2 + 1/12) - The sum of -3, 1, 12, 1, 6, 1193, 6, 7, - (-6 + 4 + 9), 119, 1, 6, - (-5 + 3 + 4), 12, - 3, 8/9, and - (-2 + 1/12) is 1357 11/12.

Therefore, the results of the given expressions are as follows: 1) -1 + 4 + 3 + 5 = 11 2) 9 + 11 - (2 + 5) - 3 - 20 + 21 + 3 + 7 = 23 3) -8 + 9 + 14 + 3 + 3 + 7 = 28 4) 7 + 5 + 12 - (-3 + 7 + 24) = 38 5) 6 - 6 + 11 + 12 - (-8 + 13 + 18) + 7 = 59 6) 5 + 12 - (10 + 8) - 11 + 7 + 9 + 8 + 2 + 15 = 49 7) -3 + 1 + 12 + 1 + 6 + 1193 + 6 + 7 - (-6 + 4 + 9) + 119 + 1 + 6 - (-5 + 3 + 4) + 12 - 3 + 8/9 - (-2 + 1/12) = 1357 11/12

I hope this helps! Let me know if you have any other questions.
