Explanation:
We are using the
lattice multiplication method, but since the problems are all two-digit × one-digit (or even one-digit × one-digit in some cases), we can solve them directly — and verify using lattice logic if needed.
Let’s go one by one, carefully:
1)
32 × 6
Break 32 into 30 + 2.
30 × 6 = 180
2 × 6 = 12
Add: 180 + 12 =
192
2)
45 × 2
40 × 2 = 80
5 × 2 = 10
80 + 10 =
90
3)
18 × 7
10 × 7 = 70
8 × 7 = 56
70 + 56 =
126
4)
67 × 3
60 × 3 = 180
7 × 3 = 21
180 + 21 =
201
5)
53 × 8
50 × 8 = 400
3 × 8 = 24
400 + 24 =
424
6)
92 × 4
90 × 4 = 360
2 × 4 = 8
360 + 8 =
368
Let me double-check each:
1) 32 × 6:
6 × 2 = 12 → write 2, carry 1
6 × 3 = 18 + 1 = 19 → so 192
✔
2) 45 × 2:
2 × 5 = 10 → 0, carry 1
2 × 4 = 8 + 1 = 9 → 90
✔
3) 18 × 7:
7 × 8 = 56 → 6, carry 5
7 × 1 = 7 + 5 = 12 → 126
✔
4) 67 × 3:
3 × 7 = 21 → 1, carry 2
3 × 6 = 18 + 2 = 20 → 201
✔
5) 53 × 8:
8 × 3 = 24 → 4, carry 2
8 × 5 = 40 + 2 = 42 → 424
✔
6) 92 × 4:
4 × 2 = 8 → 8
4 × 9 = 36 → 368
✔
All correct.
Final Answer:
1) 192
2) 90
3) 126
4) 201
5) 424
6) 368
