Let’s solve each multiplication problem step by step. We’ll multiply the two-digit numbers carefully, using standard multiplication (also called long multiplication). Remember: multiply the top number by the ones digit of the bottom number first, then by the tens digit (and add a zero at the end), then add both results together.
We’ll go one by one:
---
1) 38 × 57
First, 38 × 7 = 266
Then, 38 × 50 = 1900 (because 5 is in the tens place → 50)
Add: 266 + 1900 =
2166
---
2) 99 × 38
99 × 8 = 792
99 × 30 = 2970
Add: 792 + 2970 =
3762
---
3) 78 × 35
78 × 5 = 390
78 × 30 = 2340
Add: 390 + 2340 =
2730
---
4) 40 × 77
40 × 7 = 280 → but since it’s 77, we do:
Actually, easier: 40 × 77 = 40 × (70 + 7) = 40×70=2800, 40×7=280 → 2800+280=
3080
Or directly: 40 × 77 = 3080
---
5) 35 × 26
35 × 6 = 210
35 × 20 = 700
Add: 210 + 700 =
910
---
6) 86 × 86
86 × 6 = 516
86 × 80 = 6880
Add: 516 + 6880 =
7396
---
7) 95 × 92
95 × 2 = 190
95 × 90 = 8550
Add: 190 + 8550 =
8740
---
8) 72 × 97
72 × 7 = 504
72 × 90 = 6480
Add: 504 + 6480 =
6984
---
9) 45 × 41
45 × 1 = 45
45 × 40 = 1800
Add: 45 + 1800 =
1845
---
10) 95 × 13
95 × 3 = 285
95 × 10 = 950
Add: 285 + 950 =
1235
---
11) 49 × 92
49 × 2 = 98
49 × 90 = 4410
Add: 98 + 4410 =
4508
---
12) 84 × 65
84 × 5 = 420
84 × 60 = 5040
Add: 420 + 5040 =
5460
---
13) 10 × 37
Easy! 10 × anything just adds a zero →
370
---
14) 58 × 33
58 × 3 = 174
58 × 30 = 1740
Add: 174 + 1740 =
1914
---
15) 29 × 42
29 × 2 = 58
29 × 40 = 1160
Add: 58 + 1160 =
1218
---
16) 36 × 86
36 × 6 = 216
36 × 80 = 2880
Add: 216 + 2880 =
3096
---
17) 87 × 57
87 × 7 = 609
87 × 50 = 4350
Add: 609 + 4350 =
4959
---
18) 36 × 62
36 × 2 = 72
36 × 60 = 2160
Add: 72 + 2160 =
2232
---
19) 49 × 53
49 × 3 = 147
49 × 50 = 2450
Add: 147 + 2450 =
2597
---
20) 50 × 94
50 × 94 = half of 100 × 94 = half of 9400 =
4700
Or: 50 × 90 = 4500, 50 × 4 = 200 → 4500 + 200 =
4700
---
21) 72 × 96
72 × 6 = 432
72 × 90 = 6480
Add: 432 + 6480 =
6912
---
22) 72 × 95
72 × 5 = 360
72 × 90 = 6480
Add: 360 + 6480 =
6840
---
23) 74 × 58
74 × 8 = 592
74 × 50 = 3700
Add: 592 + 3700 =
4292
---
24) 29 × 95
29 × 5 = 145
29 × 90 = 2610
Add: 145 + 2610 =
2755
---
25) 85 × 43
85 × 3 = 255
85 × 40 = 3400
Add: 255 + 3400 =
3655
---
26) 76 × 45
76 × 5 = 380
76 × 40 = 3040
Add: 380 + 3040 =
3420
---
27) 16 × 57
16 × 7 = 112
16 × 50 = 800
Add: 112 + 800 =
912
---
28) 54 × 24
54 × 4 = 216
54 × 20 = 1080
Add: 216 + 1080 =
1296
---
29) 13 × 46
13 × 6 = 78
13 × 40 = 520
Add: 78 + 520 =
598
---
30) 57 × 22
57 × 2 = 114
57 × 20 = 1140
Add: 114 + 1140 =
1254
