Let’s solve each multiplication problem step by step. We’ll do 3-digit × 2-digit multiplication using the standard algorithm — multiply by the ones digit first, then by the tens digit (remembering to shift one place left), and add the results.

Problem 1: 410 × 64
Step 1: Multiply 410 by 4 →
410 × 4 = 1640
Step 2: Multiply 410 by 60 (since 6 is in the tens place) →
410 × 60 = 24600
Step 3: Add them →
1640 + 24600 = 26240
✔ Final answer for this:
26240

Problem 2: 695 × 80
Note: Multiplying by 80 is same as multiplying by 8 and adding a zero at the end.
Step 1: 695 × 8 = 5560
Step 2: Add a zero → 55600
✔ Final answer for this:
55600

Problem 3: 788 × 47
Step 1: 788 × 7 = ?
700×7=4900, 80×7=560, 8×7=56 → 4900+560=5460+56=5516
Step 2: 788 × 40 = ?
788 × 4 = 3152 → add zero → 31520
Step 3: Add → 5516 + 31520 = 37036
✔ Final answer for this:
37036

Problem 4: 442 × 98
Step 1: 442 × 8 = ?
400×8=3200, 40×8=320, 2×8=16 → 3200+320=3520+16=3536
Step 2: 442 × 90 = ?
442 × 9 = 3978 → add zero → 39780
Step 3: Add → 3536 + 39780 = 43316
✔ Final answer for this:
43316

Problem 5: 515 × 51
Step 1: 515 × 1 = 515
Step 2: 515 × 50 = ?
515 × 5 = 2575 → add zero → 25750
Step 3: Add → 515 + 25750 = 26265
✔ Final answer for this:
26265

Problem 6: 941 × 83
Step 1: 941 × 3 = ?
900×3=2700, 40×3=120, 1×3=3 → 2700+120=2820+3=2823
Step 2: 941 × 80 = ?
941 × 8 = 7528 → add zero → 75280
Step 3: Add → 2823 + 75280 = 78103
✔ Final answer for this:
78103

Problem 7: 584 × 22
Step 1: 584 × 2 = 1168
Step 2: 584 × 20 = 11680 (just add a zero to previous result)
Step 3: Add → 1168 + 11680 = 12848
✔ Final answer for this:
12848

Problem 8: 853 × 29
Step 1: 853 × 9 = ?
800×9=7200, 50×9=450, 3×9=27 → 7200+450=7650+27=7677
Step 2: 853 × 20 = ?
853 × 2 = 1706 → add zero → 17060
Step 3: Add → 7677 + 17060 = 24737
✔ Final answer for this:
24737

Problem 9: 772 × 86
Step 1: 772 × 6 = ?
700×6=4200, 70×6=420, 2×6=12 → 4200+420=4620+12=4632
Step 2: 772 × 80 = ?
772 × 8 = 6176 → add zero → 61760
Step 3: Add → 4632 + 61760 = 66392
✔ Final answer for this:
66392
