Step 18: 3553 + 209 = 3762
Step 19: 3762 + 209 = 3971
Step 20: 3971 + 209 = 4180
Step 21: 4180 + 209 = 4389
Step 22: 4389 + 209 = 4598
Step 23: 4598 + 209 = 4807
Step 24: 4807 + 209 = 5016
Step 25: 5016 + 209 = 5225
Step 26: 5225 + 209 = 5434
Step 27: 5434 + 209 = 5643
Step 28: 5643 + 209 = 5852
Step 29: 5852 + 209 = 6061
Step 30: 6061 + 209 = 6270
Step 31: 6270 + 209 = 6479
Step 32: 6479 + 209 = 6688
Step 33: 6688 + 209 = 6897
Step 34: 6897 + 209 = 7106
Step 35: 7106 + 209 = 7315
Step 36: 7315 + 209 = 7524
Step 37: 7524 + 209 = 7733
Step 38: 7733 + 209 = 7942
Step 39: 7942 + 209 = 8151
Step 40: 8151 + 209 = 8360
Step 41: 8360 + 209 = 8569
Step 42: 8569 + 209 = 8778
Step 43: 8778 + 209 = 8987
Step 44: 8987 + 209 = 9196
Step 45: 9196 + 209 = 9405
Step 46: 9405 + 209 = 9614
Step 47: 9614 + 209 = 9823
Step 48: 9823 + 209 = 10032
Step 49: 10032 + 209 = 10241
Step 50: 10241 + 209 = 10450
Step 51: 10450 + 209 = 10659
Step 52: 10659 + 209 = 10868
Step 53: 10868 + 209 = 11077
Step 54: 11077 + 209 = 11286
Step 55: 11286 + 209 = 11495

So, 209*55 = 11495
