OK, let's crack this. We're given 107 and our task is to multiply it by 46. Essentially, we'll be adding 107 to itself 46 times.
Step 1: 0 + 107 = 107
Step 2: 107 + 107 = 214
Step 3: 214 + 107 = 321
Step 4: 321 + 107 = 428
Step 5: 428 + 107 = 535
Step 6: 535 + 107 = 642
Step 7: 642 + 107 = 749
Step 8: 749 + 107 = 856
Step 9: 856 + 107 = 963
Step 10: 963 + 107 = 1070
Step 11: 1070 + 107 = 1177
Step 12: 1177 + 107 = 1284
Step 13: 1284 + 107 = 1391
Step 14: 1391 + 107 = 1498
Step 15: 1498 + 107 = 1605
Step 16: 1605 + 107 = 1712
Step 17: 1712 + 107 = 1819
Step 18: 1819 + 107 = 1926
Step 19: 1926 + 107 = 2033
Step 20: 2033 + 107 = 2140
Step 21: 2140 + 107 = 2247
Step 22: 2247 + 107 = 2354
Step 23: 2354 + 107 = 2461
Step 24: 2461 + 107 = 2568
Step 25: 2568 + 107 = 2675
Step 26: 2675 + 107 = 2782
Step 27: 2782 + 107 = 2889
Step 28: 2889 + 107 = 2996
Step 29: 2996 + 107 = 3103
Step 30: 3103 + 107 = 3210
Step 31: 3210 + 107 = 3317
Step 32: 3317 + 107 = 3424
Step 33: 3424 + 107 = 3531
Step 34: 3531 + 107 = 3638
Step 35: 3638 + 107 = 3745
Step 36: 3745 + 107 = 3852
Step 37: 3852 + 107 = 3959
Step 38: 3959 + 107 = 4066
Step 39: 4066 + 107 = 4173
Step 40: 4173 + 107 = 4280
Step 41: 4280 + 107 = 4387
Step 42: 4387 + 107 = 4494
Step 43: 4494 + 107 = 4601
Step 44: 4601 + 107 = 4708
Step 45: 4708 + 107 = 4815
Step 46: 4815 + 107 = 4922

So, 107*46 = 4922
