Adding Positive and Subtracting Integers | Integer Worksheets - Free Printable

Let’s solve each problem step by step. Remember:
- Adding a negative is like subtracting.
- Subtracting a negative is like adding.
- Use the number line in your head if it helps!

A) 8 – 4 =
Start at 8, go back 4 → 4

B) 5 + 2 =
Just add → 7

C) 9 + (-3) =
Adding -3 is same as subtracting 3 → 9 – 3 = 6

D) 6 – 11 =
Start at 6, go back 11 → you pass 0 and land on -5

E) -7 + 5 =
Start at -7, move right 5 → lands on -2

F) 8 – (-8) =
Subtracting -8 is same as adding 8 → 8 + 8 = 16

G) -12 + (-4) =
Adding -4 means go left 4 from -12 → -16

H) -3 – 5 =
Start at -3, go left 5 more → -8

I) 10 + (-5) =
Same as 10 – 5 → 5

J) -7 – 3 =
Start at -7, go left 3 → -10

---

K) -15 – (-15) =
Subtracting -15 is same as adding 15 → -15 + 15 = 0

L) -17 + (-4) =
Add -4 to -17 → go left 4 from -17 → -21

M) -12 – 16 =
Start at -12, go left 16 → -28

N) 19 – (-5) =
Subtracting -5 is same as adding 5 → 19 + 5 = 24

O) -13 + 9 =
Start at -13, move right 9 → lands on -4

P) -20 + 20 =
They cancel out → 0

Q) 28 – (-11) =
Subtracting -11 is same as adding 11 → 28 + 11 = 39

R) -18 – (-16) =
Subtracting -16 is same as adding 16 → -18 + 16 = -2

S) -25 + (-8) =
Add -8 to -25 → go left 8 from -25 → -33

T) -13 – (-5) =
Subtracting -5 is same as adding 5 → -13 + 5 = -8
