Alright, let's solve this math problem step by step. First, we have the number 209. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 40. So, we're going to take the number 209 and add it 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
