Let's solve each addition and subtraction problem step by step.
---
Top Left Column:
1.
6 + 2 = 8
Adding 2 to 6 gives 8.
2.
2 + 6 = 8
Addition is commutative, so 2 + 6 is also 8.
3.
8 - 2 = 6
Subtracting 2 from 8 leaves 6.
4.
8 - 6 = 2
Subtracting 6 from 8 leaves 2.
---
Top Right Column:
5.
5 + 3 = 8
Adding 3 to 5 gives 8.
6.
3 + 5 = 8
Again, commutative property — same as above.
7.
8 - 3 = 5
Subtracting 3 from 8 gives 5.
8.
8 - 5 = 3
Subtracting 5 from 8 gives 3.
---
Bottom Left Column:
9.
4 + 2 = 6
Adding 2 to 4 gives 6.
10.
2 + 4 = 6
Commutative property — same result.
11.
6 - 2 = 4
Subtracting 2 from 6 gives 4.
12.
6 - 4 = 2
Subtracting 4 from 6 gives 2.
---
Bottom Right Column:
13.
7 + 1 = 8
Adding 1 to 7 gives 8.
14.
1 + 7 = 8
Commutative property again.
15.
8 - 1 = 7
Subtracting 1 from 8 gives 7.
16.
8 - 7 = 1
Subtracting 7 from 8 gives 1.

✔ Final Answers:
```
Addition and Subtraction
6 + 2 = 8 | 5 + 3 = 8
2 + 6 = 8 | 3 + 5 = 8
8 - 2 = 6 | 8 - 3 = 5
8 - 6 = 2 | 8 - 5 = 3
4 + 2 = 6 | 7 + 1 = 8
2 + 4 = 6 | 1 + 7 = 8
6 - 2 = 4 | 8 - 1 = 7
6 - 4 = 2 | 8 - 7 = 1
```
All problems are solved using basic arithmetic facts. The key concepts used:
-
Commutative property of addition: a + b = b + a.
-
Basic subtraction facts: knowing how much to subtract to get the difference.
