FREE Printable Adding And Subtracting Integers Worksheets [PDFs] - Free Printable

Let’s solve each problem step by step. We’re adding and subtracting integers — remember:

- Adding a positive number: move right on the number line.
- Adding a negative number: move left (same as subtracting).
- Subtracting a negative number: same as adding (because minus minus = plus).

We’ll go one by one.

1) -9 + 19 + 13

Start with -9 + 19 = 10
Then 10 + 13 = 23

---

2) 12 + (-4) + (-15)

12 + (-4) = 8
8 + (-15) = -7 → (-7)

---

3) 0 + 14 - (-8)

0 + 14 = 14
14 - (-8) = 14 + 8 = 22

---

4) -17 + (-3) + (-9)

-17 + (-3) = -20
-20 + (-9) = -29

---

5) 19 - 3 + 0

19 - 3 = 16
16 + 0 = 16

---

6) 2 + 3 - (-9)

2 + 3 = 5
5 - (-9) = 5 + 9 = 14

---

7) -19 + 8 + (-6)

-19 + 8 = -11
-11 + (-6) = -17

---

8) -10 - (-20) + (-4)

-10 - (-20) = -10 + 20 = 10
10 + (-4) = 6

---

9) -13 + (-19) + (-10)

-13 + (-19) = -32
-32 + (-10) = -42

---

10) -16 + (-1) + (-7)

-16 + (-1) = -17
-17 + (-7) = -24

---

11) -1 - 5 + 20

-1 - 5 = -6
-6 + 20 = 14

---

12) 18 - (-2) + (-20)

18 - (-2) = 18 + 2 = 20
20 + (-20) = 0

---

13) 14 - 14 + 14

14 - 14 = 0
0 + 14 = 14

---

14) 13 + 5 - 7

13 + 5 = 18
18 - 7 = 11

---

15) 14 - 19 + 2

14 - 19 = -5
-5 + 2 = -3

---

16) 2 - 19 - (-18)

2 - 19 = -17
-17 - (-18) = -17 + 18 = 1

---

17) -5 + (-12) - 6

-5 + (-12) = -17
-17 - 6 = -23

---

18) -7 + (-17) + (-5)

-7 + (-17) = -24
-24 + (-5) = -29

---

19) -7 + (-4) - 9

-7 + (-4) = -11
-11 - 9 = -20

---

20) -15 + 0 - (-18)

-15 + 0 = -15
-15 - (-18) = -15 + 18 = 3

---
