Let’s solve each problem one by one. We’ll do multiplication and division carefully, step by step.
---
First row (multiplication):
1.
12 × 23
Break it down:
12 × 20 = 240
12 × 3 = 36
Add them: 240 + 36 =
276
2.
15 × 14
15 × 10 = 150
15 × 4 = 60
150 + 60 =
210
3.
20 × 11
20 × 10 = 200
20 × 1 = 20
200 + 20 =
220
4.
18 × 10
Just add a zero:
180
5.
16 × 20
16 × 2 = 32, then add a zero →
320
---
Second row (multiplication):
6.
17 × 12
17 × 10 = 170
17 × 2 = 34
170 + 34 =
204
7.
11 × 22
11 × 20 = 220
11 × 2 = 22
220 + 22 =
242
8.
13 × 17
Let’s do 13 × 10 = 130
13 × 7 = 91
130 + 91 =
221
9.
21 × 14
21 × 10 = 210
21 × 4 = 84
210 + 84 =
294
10.
19 × 19
This is 19 squared.
20 × 19 = 380, minus 19 =
361
Or: 19 × 10 = 190, 19 × 9 = 171 → 190 + 171 =
361

Third row (division):
11.
88 ÷ 22
How many times does 22 go into 88?
22 × 4 = 88 →
4
12.
42 ÷ 21
21 × 2 = 42 →
2
13.
96 ÷ 12
12 × 8 = 96 →
8
14.
60 ÷ 15
15 × 4 = 60 →
4
15.
63 ÷ 21
21 × 3 = 63 →
3
---
Fourth row (division):
16.
264 ÷ 22
Let’s think: 22 × 10 = 220
264 - 220 = 44
22 × 2 = 44
So 10 + 2 =
12
17.
325 ÷ 13
Try 13 × 20 = 260
325 - 260 = 65
13 × 5 = 65
So 20 + 5 =
25
18.
144 ÷ 12
12 × 12 = 144 →
12
---
Fifth row (division):
19.
224 ÷ 14
14 × 10 = 140
224 - 140 = 84
14 × 6 = 84
So 10 + 6 =
16
20.
170 ÷ 10
Just remove the zero →
17
21.
255 ÷ 15
15 × 10 = 150
255 - 150 = 105
15 × 7 = 105
So 10 + 7 =
17
---
Sixth row (multiplication):
22.
25 × 16
25 × 4 = 100, so 25 × 16 = 25 × 4 × 4 = 100 × 4 =
400
23.
14 × 28
Break it: 14 × 20 = 280
14 × 8 = 112
280 + 112 =
392
24.
12 × 31
12 × 30 = 360
12 × 1 = 12
360 + 12 =
372
---
Now let’s list all answers in order as they appear on the sheet:
Row 1: 276, 210, 220, 180, 320
Row 2: 204, 242, 221, 294, 361
Row 3: 4, 2, 8, 4, 3
Row 4: 12, 25, 12
Row 5: 16, 17, 17
Row 6: 400, 392, 372
Double-checking a few tricky ones:
- 19×19=361 ✔️
- 264÷22=12 ✔️ (22×12=264)
- 325÷13=25 ✔️ (13×25=325)
- 25×16=400 ✔️
- 14×28=392 ✔️ (14×30=420 minus 14×2=28 → 420-28=392)
All correct!
Final Answer:
276, 210, 220, 180, 320, 204, 242, 221, 294, 361, 4, 2, 8, 4, 3, 12, 25, 12, 16, 17, 17, 400, 392, 372
