1. 123 × 40

We can break this down:
123 × 40 = 123 × (4 × 10) = (123 × 4) × 10

First, 123 × 4:
3 × 4 = 12 → write 2, carry 1
2 × 4 = 8 + 1 = 9
1 × 4 = 4
→ So, 123 × 4 = 492

Now multiply by 10: 492 × 10 = 4920

✔ Answer: 4920

2. 248 × 14

Break it into: 248 × (10 + 4) = (248 × 10) + (248 × 4)

248 × 10 = 2480
248 × 4:
8 × 4 = 32 → write 2, carry 3
4 × 4 = 16 + 3 = 19 → write 9, carry 1
2 × 4 = 8 + 1 = 9
→ 248 × 4 = 992

Now add: 2480 + 992
2480 + 900 = 3380
3380 + 92 = 3472

✔ Answer: 3472

3. 663 × 25

Note: 25 = 100 ÷ 4, so we can do 663 × 100 = 66300, then divide by 4.

66300 ÷ 4:
66300 ÷ 2 = 33150
33150 ÷ 2 = 16575

Or directly:
663 × 25 = 663 × (20 + 5) = (663 × 20) + (663 × 5)

663 × 20 = 13260
663 × 5:
3 × 5 = 15 → write 5, carry 1
6 × 5 = 30 + 1 = 31 → write 1, carry 3
6 × 5 = 30 + 3 = 33 → 3315

Add: 13260 + 3315
13260 + 3000 = 16260
16260 + 315 = 16575

✔ Answer: 16575

4. 388 × 56

Break into: 388 × (50 + 6) = (388 × 50) + (388 × 6)

388 × 50 = 388 × 5 × 10
388 × 5:
8 × 5 = 40 → write 0, carry 4
8 × 5 = 40 + 4 = 44 → write 4, carry 4
3 × 5 = 15 + 4 = 19 → 1940
Then ×10 → 19400? Wait — no! Actually, 388 × 5 = 1940, then ×10 for 50? No — 50 is already accounted for.

Wait — better way:

388 × 50 = 388 × 5 × 10 = (1940) × 10 = 19400? That’s wrong because 388 × 5 = 1940, and 1940 × 10 = 19400 — but that’s for 50? Yes, correct.

Actually: 388 × 50 = 19400? Let me check: 400 × 50 = 20000, 12 × 50 = 600, so 20000 - 600 = 19400 — yes.

Now 388 × 6:
8 × 6 = 48 → write 8, carry 4
8 × 6 = 48 + 4 = 52 → write 2, carry 5
3 × 6 = 18 + 5 = 23 → 2328

Now add: 19400 + 2328
19400 + 2000 = 21400
21400 + 328 = 21728

✔ Answer: 21728

5. 879 × 62

Break into: 879 × (60 + 2) = (879 × 60) + (879 × 2)

879 × 60 = 879 × 6 × 10
879 × 6:
9 × 6 = 54 → write 4, carry 5
7 × 6 = 42 + 5 = 47 → write 7, carry 4
8 × 6 = 48 + 4 = 52 → 5274
Then ×10 → 52740

879 × 2 = 1758

Add: 52740 + 1758
52740 + 1000 = 53740
53740 + 700 = 54440
54440 + 58 = 54498

✔ Answer: 54498

6. 524 × 38

Break into: 524 × (30 + 8) = (524 × 30) + (524 × 8)

524 × 30 = 524 × 3 × 10
524 × 3:
4 × 3 = 12 → write 2, carry 1
2 × 3 = 6 + 1 = 7
5 × 3 = 15 → 1572
×10 → 15720

524 × 8:
4 × 8 = 32 → write 2, carry 3
2 × 8 = 16 + 3 = 19 → write 9, carry 1
5 × 8 = 40 + 1 = 41 → 4192

Add: 15720 + 4192
15720 + 4000 = 19720
19720 + 192 = 19912

✔ Answer: 19912

7. 853 × 26

Break into: 853 × (20 + 6) = (853 × 20) + (853 × 6)

853 × 20 = 853 × 2 × 10
853 × 2 = 1706
×10 → 17060

853 × 6:
3 × 6 = 18 → write 8, carry 1
5 × 6 = 30 + 1 = 31 → write 1, carry 3
8 × 6 = 48 + 3 = 51 → 5118

Add: 17060 + 5118
17060 + 5000 = 22060
22060 + 118 = 22178

✔ Answer: 22178

8. 985 × 15

Break into: 985 × (10 + 5) = (985 × 10) + (985 × 5)

985 × 10 = 9850
985 × 5:
5 × 5 = 25 → write 5, carry 2
8 × 5 = 40 + 2 = 42 → write 2, carry 4
9 × 5 = 45 + 4 = 49 → 4925

Add: 9850 + 4925
9850 + 4000 = 13850
13850 + 925 = 14775

✔ Answer: 14775

9. 452 × 58

Break into: 452 × (50 + 8) = (452 × 50) + (452 × 8)

452 × 50 = 452 × 5 × 10
452 × 5:
2 × 5 = 10 → write 0, carry 1
5 × 5 = 25 + 1 = 26 → write 6, carry 2
4 × 5 = 20 + 2 = 22 → 2260
×10 → 22600

452 × 8:
2 × 8 = 16 → write 6, carry 1
5 × 8 = 40 + 1 = 41 → write 1, carry 4
4 × 8 = 32 + 4 = 36 → 3616

Add: 22600 + 3616
22600 + 3000 = 25600
25600 + 616 = 26216

✔ Answer: 26216
