Part 1: Find the sum (addition)
We’ll go row by row.
First row:
- 3 + 2 =
5
- 3 + 4 =
7
- 3 + 5 =
8
- 3 + 6 =
9
- 3 + 7 =
10
- 4 + 1 =
5
- 4 + 2 =
6
Second row:
- 4 + 3 =
7
- 4 + 4 =
8
- 4 + 5 =
9
- 4 + 6 =
10
- 5 + 1 =
6
- 5 + 2 =
7
- 5 + 3 =
8
Third row:
- 5 + 4 =
9
- 5 + 5 =
10
- 6 + 1 =
7
- 6 + 2 =
8
- 6 + 3 =
9
- 6 + 4 =
10
- 7 + 1 =
8

Part 2: Find the difference (subtraction)
First row:
- 4 - 1 =
3
- 4 - 2 =
2
- 4 - 3 =
1
- 4 - 4 =
0
- 5 - 1 =
4
- 5 - 2 =
3
- 5 - 3 =
2
Second row:
- 5 - 4 =
1
- 5 - 5 =
0
- 6 - 1 =
5
- 6 - 2 =
4
- 6 - 3 =
3
- 6 - 4 =
2
- 6 - 5 =
1
Third row:
- 6 - 6 =
0
- 7 - 1 =
6
- 7 - 2 =
5
- 8 - 1 =
7
- 8 - 2 =
6
- 9 - 0 =
9
- 9 - 1 =
8
