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

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

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

Subtraction Problems:
10.
958 - 639
8 - 9 → can’t do, borrow → 18 - 9 = 9 (tens digit becomes 4)
4 - 3 = 1
9 - 6 = 3
Result:
319
11.
506 - 258
6 - 8 → borrow → 16 - 8 = 8 (hundreds digit becomes 4, tens become 9)
9 - 5 = 4
4 - 2 = 2
Result:
248
12.
786 - 207
6 - 7 → borrow → 16 - 7 = 9 (tens digit becomes 7)
7 - 0 = 7
7 - 2 = 5
Result:
579

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