Since both ExplainAnswer and TeachTopic are false, and GeneratePractice is also false, we will only provide the Final Answer — which in this case means solving all the problems on the worksheet accurately.

We’ll go section by section, compute each answer carefully, and list them in order.

Section A:

1) 2 – 7 = -5
2) -4 + 8 = 4
3) -2 + 12 = 10
4) -7 – 4 = -11
5) 9 – 10 = -1
6) -7 + 4 = -3
7) -8 – 11 = -19
8) -15 + 1 = -14
9) -12 + 14 = 2
10) -10 + 23 = 13
11) -6 – 11 = -17
12) -12 – 17 = -29

Section B:

1) 2 + (-6) = -4
2) -9 – (+9) = -9 – 9 = -18
3) 4 + (-3) = 1
4) 3 – (+8) = 3 – 8 = -5
5) -2 + (-4) = -6
6) -5 – (+5) = -5 – 5 = -10
7) 3 – (-4) = 3 + 4 = 7
8) 8 – (-5) = 8 + 5 = 13
9) 10 – (-6) = 10 + 6 = 16
10) -7 – (-3) = -7 + 3 = -4
11) -1 – (-3) = -1 + 3 = 2
12) -6 – (-2) = -6 + 2 = -4

---

Section C:

1) -8 – (-12) = -8 + 12 = 4
2) -8 + (-10) = -18
3) -16 – (+7) = -16 – 7 = -23
4) 27 + (-5) = 22
5) -17 – (-3) = -17 + 3 = -14
6) -3 – (-14) = -3 + 14 = 11
7) -17 + (-9) = -26
8) -8 – (+19) = -8 – 19 = -27
9) -54 – (+24) = -54 – 24 = -78
10) -10 – (-8) = -10 + 8 = -2
11) 9 – (+20) = 9 – 20 = -11
12) -18 – (-33) = -18 + 33 = 15

---

Section D:

1) 7 – (+2) – (-4) = 7 – 2 + 4 = 9
2) -5 – (-4) + (-2) = -5 + 4 – 2 = -3
3) 4 + (-6) – (-7) = 4 – 6 + 7 = 5
4) -3 – (-9) + (-9) = -3 + 9 – 9 = -3
5) 18 + (-3) – (-4) = 18 – 3 + 4 = 19
6) 2 + (5 – (-3)) = 2 + (5 + 3) = 2 + 8 = 10
7) -11 + (-8 – (-2)) = -11 + (-8 + 2) = -11 + (-6) = -17
8) 7 – (-2 + (-6)) = 7 – (-8) = 7 + 8 = 15
9) (-4 + (-2)) + (4 – (-9)) = (-6) + (4 + 9) = -6 + 13 = 7
10) 3 – ((-1 + (-5)) – 12) = 3 – ((-6) – 12) = 3 – (-18) = 3 + 18 = 21
