Let’s solve each multiplication problem step by step. We’re multiplying 2-digit numbers by 6.
We’ll go row by row, left to right.

First Row:
1.
18 × 6
Break it down: (10 × 6) + (8 × 6) = 60 + 48 =
108
2.
39 × 6
(30 × 6) + (9 × 6) = 180 + 54 =
234
3.
89 × 6
(80 × 6) + (9 × 6) = 480 + 54 =
534
4.
46 × 6
(40 × 6) + (6 × 6) = 240 + 36 =
276
5.
15 × 6
(10 × 6) + (5 × 6) = 60 + 30 =
90

Second Row:
6.
56 × 6
(50 × 6) + (6 × 6) = 300 + 36 =
336
7.
43 × 6
(40 × 6) + (3 × 6) = 240 + 18 =
258
8.
30 × 6
3 × 6 = 18, so 30 × 6 =
180
9.
87 × 6
(80 × 6) + (7 × 6) = 480 + 42 =
522
10.
68 × 6
(60 × 6) + (8 × 6) = 360 + 48 =
408

Third Row:
11.
11 × 6
(10 × 6) + (1 × 6) = 60 + 6 =
66
12.
50 × 6
5 × 6 = 30, so 50 × 6 =
300
13.
55 × 6
(50 × 6) + (5 × 6) = 300 + 30 =
330
14.
98 × 6
(90 × 6) + (8 × 6) = 540 + 48 =
588
15.
52 × 6
(50 × 6) + (2 × 6) = 300 + 12 =
312

Fourth Row:
16.
78 × 6
(70 × 6) + (8 × 6) = 420 + 48 =
468
17.
51 × 6
(50 × 6) + (1 × 6) = 300 + 6 =
306
18.
55 × 6 ← already done above →
330
19.
84 × 6
(80 × 6) + (4 × 6) = 480 + 24 =
504
20.
26 × 6
(20 × 6) + (6 × 6) = 120 + 36 =
156
---
Fifth Row:
21.
86 × 6
(80 × 6) + (6 × 6) = 480 + 36 =
516
22.
23 × 6
(20 × 6) + (3 × 6) = 120 + 18 =
138
23.
85 × 6
(80 × 6) + (5 × 6) = 480 + 30 =
510
24.
14 × 6
(10 × 6) + (4 × 6) = 60 + 24 =
84
25.
48 × 6
(40 × 6) + (8 × 6) = 240 + 48 =
288
