OK, let's crack this. We're given 862 and our task is to multiply it by 35. Essentially, we'll be adding 862 to itself 35 times.
Step 1: 0 + 862 = 862
Step 2: 862 + 862 = 1724
Step 3: 1724 + 862 = 2586
Step 4: 2586 + 862 = 3448
Step 5: 3448 + 862 = 4310
Step 6: 4310 + 862 = 5172
Step 7: 5172 + 862 = 6034
Step 8: 6034 + 862 = 6896
Step 9: 6896 + 862 = 7758
Step 10: 7758 + 862 = 8620
Step 11: 8620 + 862 = 9482
Step 12: 9482 + 862 = 10344
Step 13: 10344 + 862 = 11206
Step 14: 11206 + 862 = 12068
Step 15: 12068 + 862 = 12930
Step 16: 12930 + 862 = 13792
Step 17: 13792 + 862 = 14654
Step 18: 14654 + 862 = 15516
Step 19: 15516 + 862 = 16378
Step 20: 16378 + 862 = 17240
Step 21: 17240 + 862 = 18102
Step 22: 18102 + 862 = 18964
Step 23: 18964 + 862 = 19826
Step 24: 19826 + 862 = 20688
Step 25: 20688 + 862 = 21550
Step 26: 21550 + 862 = 22412
Step 27: 22412 + 862 = 23274
Step 28: 23274 + 862 = 24136
Step 29: 24136 + 862 = 24998
Step 30: 24998 + 862 = 25860
Step 31: 25860 + 862 = 26722
Step 32: 26722 + 862 = 27584
Step 33: 27584 + 862 = 28446
Step 34: 28446 + 862 = 29308
Step 35: 29308 + 862 = 30170

So, 862*35 = 30170
