Absolutely! Let’s solve each problem step by step, following the rules for
adding and subtracting integers.
---
🔢 Key Rules to Remember:
1.
Adding two numbers with the same sign: Add their absolute values, keep the sign.
2.
Adding two numbers with different signs: Subtract the smaller absolute value from the larger, keep the sign of the number with the larger absolute value.
3.
Subtracting a number: Change the subtraction to addition of the opposite (additive inverse).
→ `a - b = a + (-b)`
→ `a - (-b) = a + b`

Let’s go row by row:

##
✔ Row 1:
1.
3 + (-8)
→ Different signs: |8| > |3| → 8 - 3 = 5, sign is negative →
-5
2.
(-9) - (-4)
→ Subtracting negative = adding positive: -9 + 4
→ Different signs: |9| > |4| → 9 - 4 = 5, sign is negative →
-5
3.
7 - 5
→ Simple subtraction →
2

##
✔ Row 2:
4.
6 - (-4)
→ 6 + 4 =
10
5.
(-4) - (-2)
→ -4 + 2 =
-2
6.
(-4) - 10
→ -4 + (-10) =
-14

##
✔ Row 3:
7.
6 - 5
→
1
8.
(-2) - 5
→ -2 + (-5) =
-7
9.
(-2) - 7
→ -2 + (-7) =
-9

##
✔ Row 4:
10.
(-8) + (-2)
→ Same sign: 8 + 2 = 10, negative →
-10
11.
8 + 6
→
14
12.
(-9) + 10
→ Different signs: 10 - 9 = 1, positive →
1
---
##
✔ Row 5:
13.
8 + (-10)
→ 10 - 8 = 2, negative →
-2
14.
2 - (-10)
→ 2 + 10 =
12
15.
8 - 5
→
3

##
✔ Row 7:
19.
(-2) + 6
→ 6 - 2 = 4, positive →
4
20.
(-4) - 4
→ -4 + (-4) =
-8
21.
9 - (-7)
→ 9 + 7 =
16

##
✔ Row 8:
22.
(-1) - 0
→ -1 + 0 =
-1
23.
7 - 5
→
2
24.
(-5) + (-10)
→ Same sign: 5 + 10 = 15, negative →
-15
---
##
✔ Row 9:
25.
(-1) - (-2)
→ -1 + 2 =
1
26.
(-5) - (-6)
→ -5 + 6 =
1
27.
9 - (-9)
→ 9 + 9 =
18
