Let’s solve each problem one by one. We’re adding integers — that means positive and negative numbers. Remember:
- If both numbers are positive, just add them.
- If both are negative, add their absolute values and keep the negative sign.
- If one is positive and one is negative, subtract the smaller absolute value from the larger one, and keep the sign of the number with the larger absolute value.
We’ll go in order from 1 to 32.
---
1) -45 + 54
54 is bigger than 45, and it’s positive → 54 - 45 =
9
2) -29 + (-58)
Both negative → add 29 + 58 = 87 → answer is
-87
3) 10 + 25
Both positive → 10 + 25 =
35
4) 52 + (-25)
Positive and negative → 52 - 25 =
27
5) 86 + (-68)
86 - 68 =
18
6) 77 + (-99)
99 is bigger and negative → 99 - 77 = 22 → answer is
-22
7) 47 + (-54)
54 is bigger and negative → 54 - 47 = 7 → answer is
-7
8) 85 + (-7)
85 - 7 =
78
9) 23 + 27
23 + 27 =
50
10) 52 + (-15)
52 - 15 =
37
11) 14 + (-10)
14 - 10 =
4
12) -54 + 24
54 is bigger and negative → 54 - 24 = 30 → answer is
-30
13) 17 + 78
17 + 78 =
95
14) -66 + 62
66 is bigger and negative → 66 - 62 = 4 → answer is
-4
15) -36 + (-22)
Both negative → 36 + 22 = 58 → answer is
-58
16) 82 + (-85)
85 is bigger and negative → 85 - 82 = 3 → answer is
-3
17) -12 + 14
14 is bigger and positive → 14 - 12 =
2
18) -66 + 9
66 is bigger and negative → 66 - 9 = 57 → answer is
-57
19) 56 + (-31)
56 - 31 =
25
20) -12 + 17
17 is bigger and positive → 17 - 12 =
5
21) 15 + 38
15 + 38 =
53
22) 6 + 53
6 + 53 =
59
23) 29 + (-35)
35 is bigger and negative → 35 - 29 = 6 → answer is
-6
24) 16 + 23
16 + 23 =
39
25) 63 + (-7)
63 - 7 =
56
26) 5 + (-6)
6 is bigger and negative → 6 - 5 = 1 → answer is
-1
27) -3 + 1
3 is bigger and negative → 3 - 1 = 2 → answer is
-2
28) 20 + (-7)
20 - 7 =
13
29) -21 + 6
21 is bigger and negative → 21 - 6 = 15 → answer is
-15
30) 7 + 23
7 + 23 =
30
31) 21 + 11
21 + 11 =
32
32) -8 + (-4)
Both negative → 8 + 4 = 12 → answer is
-12
