Let’s solve each problem one by one, carefully and step by step.

Row 1: Division
1.
8 ) 112
How many times does 8 go into 11? → 1 time (8 × 1 = 8), subtract: 11 - 8 = 3
Bring down 2 → 32
How many times does 8 go into 32? → 4 times (8 × 4 = 32)
So, 112 ÷ 8 =
14
2.
9 ) 288
9 into 28 → 3 times (9×3=27), subtract: 28-27=1
Bring down 8 → 18
9 into 18 → 2 times
So, 288 ÷ 9 =
32
3.
12 ) 192
12 into 19 → 1 time (12×1=12), subtract: 19-12=7
Bring down 2 → 72
12 into 72 → 6 times
So, 192 ÷ 12 =
16

Row 2: Multiplication
4.
165 × 45
Break it: 165 × 40 + 165 × 5
165 × 5 = 825
165 × 40 = 6600
Add: 6600 + 825 =
7425
5.
352 × 24
352 × 20 = 7040
352 × 4 = 1408
Add: 7040 + 1408 =
8448
6.
287 × 57
287 × 50 = 14350
287 × 7 = 2009
Add: 14350 + 2009 =
16359

Row 3: Addition
7.
342 + 567
2+7=9, 4+6=10 (write 0 carry 1), 3+5+1=9 →
909
8.
1432 + 965
2+5=7, 3+6=9, 4+9=13 (write 3 carry 1), 1+1=2 →
2397
9.
1021 + 659
1+9=10 (write 0 carry 1), 2+5+1=8, 0+6=6, 1+0=1 →
1680

Row 4: Subtraction
10.
958 - 639
8-9 → borrow: 18-9=9, 4-3=1, 9-6=3 →
319
11.
506 - 258
6-8 → borrow: 16-8=8, 9-5=4 (since we borrowed from 0 which becomes 9 after borrowing from 5), 4-2=2 →
248
12.
786 - 207
6-7 → borrow: 16-7=9, 7-0=7, 7-2=5 →
579

Final Answer:
14, 32, 16, 7425, 8448, 16359, 909, 2397, 1680, 319, 248, 579
