Without delay, let's solve this. We've got 209 and we will be multiplying it by 40, that is, adding 209 to itself 40 times.
Step 1: 0 + 209 = 209
Step 2: 209 + 209 = 418
Step 3: 418 + 209 = 627
Step 4: 627 + 209 = 836
Step 5: 836 + 209 = 1045
Step 6: 1045 + 209 = 1254
Step 7: 1254 + 209 = 1463
Step 8: 1463 + 209 = 1672
Step 9: 1672 + 209 = 1881
Step 10: 1881 + 209 = 2090
Step 11: 2090 + 209 = 2299
Step 12: 2299 + 209 = 2508
Step 13: 2508 + 209 = 2717
Step 14: 2717 + 209 = 2926
Step 15: 2926 + 209 = 3135
Step 16: 3135 + 209 = 3344
Step 17: 3344 + 209 = 3553
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

So, 209*40 = 8360
