Let’s solve each problem one by one. We’ll go row by row, left to right.
---
Row 1:
31 - (-17) =
Subtracting a negative is like adding the positive:
31 + 17 =
48
93 - 22 =
Just subtract:
93 - 22 =
71
(-20) + 41 =
Start at -20, add 41 → move 41 steps right:
-20 + 41 =
21
---
Row 2:
20 + 62 =
Add normally:
20 + 62 =
82
82 + 38 =
82 + 38 =
120
(-8) + (-23) =
Adding two negatives: add their absolute values and keep the negative sign:
8 + 23 = 31 → so answer is
-31
---
Row 3:
87 - (-36) =
Again, subtracting negative = adding positive:
87 + 36 =
123
34 + 62 =
34 + 62 =
96
20 - (-41) =
20 + 41 =
61
---
Row 4:
3 + (-63) =
Adding a negative is like subtracting:
3 - 63 =
-60
(-63) - (-79) =
Subtracting negative = adding positive:
-63 + 79 =
16
55 + 44 =
55 + 44 =
99
---
Row 5:
(-87) - (-31) =
-87 + 31 =
-56
84 - (-37) =
84 + 37 =
121
(-43) - 71 =
This is -43 minus 71 → more negative:
-43 - 71 =
-114
---
Row 6:
(-25) - 88 =
-25 - 88 =
-113
(-56) + 91 =
Start at -56, add 91 → 91 - 56 = 35 →
35
(-39) + 47 =
47 - 39 =
8
---
Row 7:
(-3) + (-71) =
Both negative: 3 + 71 = 74 →
-74
52 + 23 =
52 + 23 =
75
(-61) - 26 =
-61 - 26 =
-87
---
Row 8:
(-3) - 33 =
-3 - 33 =
-36
(-29) + (-87) =
29 + 87 = 116 →
-116
(-2) - (-56) =
-2 + 56 =
54
---
Row 9:
24 - 50 =
24 - 50 =
-26
65 + 19 =
65 + 19 =
84
46 + 46 =
46 + 46 =
92
---
Row 10:
43 - (-6) =
43 + 6 =
49
(-20) - 37 =
-20 - 37 =
-57
12 + (-84) =
12 - 84 =
-72
---
Row 11:
5 + (-40) =
5 - 40 =
-35
75 - (-83) =
75 + 83 =
158
(-36) + (-29) =
36 + 29 = 65 →
-65
---
Final Answer:
48, 71, 21,
82, 120, -31,
123, 96, 61,
-60, 16, 99,
-56, 121, -114,
-113, 35, 8,
-74, 75, -87,
-36, -116, 54,
-26, 84, 92,
49, -57, -72,
-35, 158, -65
