Answer 2

Let's solve each of these expressions step by step:

1. 13 - 6 + 9 + 6 - 5 + 27 - (30 - 25)

First, solve the expression inside the parentheses:

30 - 25 = 5

Now, substitute this value back into the original expression:

13 - 6 + 9 + 6 - 5 + 27 - 5

Now, calculate the remaining additions and subtractions from left to right:

(13 - 6) = 7 (7 + 9) = 16 (16 + 6) = 22 (22 - 5) = 17 (17 + 27) = 44 (44 - 5) = 39

So, the answer is 39.

2. 2 + 88 + 9 - 12 - 9 - (88 + 2 + 47)

First, solve the expression inside the parentheses:

88 + 2 + 47 = 137

Now, substitute this value back into the original expression:

2 + 88 + 9 - 12 - 9 - 137

Now, calculate the remaining additions and subtractions from left to right:

(2 + 88) = 90 (90 + 9) = 99 (99 - 12) = 87 (87 - 9) = 78 (78 - 137) = -59

So, the answer is -59.

3. 46 + 4 - 31 - 4 - (29 + 6 - 30)

First, solve the expression inside the parentheses:

29 + 6 - 30 = 5

Now, substitute this value back into the original expression:

46 + 4 - 31 - 4 - 5

Now, calculate the remaining additions and subtractions from left to right:

(46 + 4) = 50 (50 - 31) = 19 (19 - 4) = 15 (15 - 5) = 10

So, the answer is 10.
