Let’s solve each problem step by step. We’ll go one at a time, carefully adding and subtracting integers (positive and negative numbers). Remember:
- Adding a positive number → move right on the number line.
- Adding a negative number → same as subtracting that positive number.
- Subtracting a negative number → same as adding that positive number.
We’ll simplify each expression from left to right unless parentheses tell us otherwise.

1) -9 + 19 + 13
Start with -9 + 19 = 10
Then 10 + 13 =
23
✔ Answer: 23
---
2) 12 + (-4) + (-15)
12 + (-4) = 8
8 + (-15) = 8 - 15 =
-7
✔ Answer: -7
---
3) 0 + 14 - (-8)
0 + 14 = 14
Subtracting a negative: 14 - (-8) = 14 + 8 =
22
✔ Answer: 22

18 - (-2) = 18 + 2 = 20
20 + (-20) = 0
✔ Answer: 0
---
13) 14 - 14 + 14
14 - 14 = 0
0 + 14 =
14
✔ Answer: 14
---
14) 13 + 5 - 7
13 + 5 = 18
18 - 7 =
11
✔ Answer: 11
---
15) 14 - 19 + 2
14 - 19 = -5
-5 + 2 =
-3
✔ Answer: -3
---
16) 2 - 19 - (-18)
2 - 19 = -17
-17 - (-18) = -17 + 18 =
1
✔ Answer: 1
---
17) -5 + (-12) - 6
-5 + (-12) = -17
-17 - 6 =
-23
✔ Answer: -23
---
18) -7 + (-17) + (-5)
-7 + (-17) = -24
-24 + (-5) = -29
✔ Answer: -29
---
19) -7 + (-4) - 9
-7 + (-4) = -11
-11 - 9 =
-20
✔ Answer: -20
---
20) -15 + 0 - (-18)
