Sure thing, let's get straight to it. We start with 207 and we're going to multiply it by 50, which means adding 207 to itself 50 times.
Step 1: 0 + 207 = 207
Step 2: 207 + 207 = 414
Step 3: 414 + 207 = 621
Step 4: 621 + 207 = 828
Step 5: 828 + 207 = 1035
Step 6: 1035 + 207 = 1242
Step 7: 1242 + 207 = 1449
Step 8: 1449 + 207 = 1656
Step 9: 1656 + 207 = 1863
Step 10: 1863 + 207 = 2070
Step 11: 2070 + 207 = 2277
Step 12: 2277 + 207 = 2484
Step 13: 2484 + 207 = 2691
Step 14: 2691 + 207 = 2898
Step 15: 2898 + 207 = 3105
Step 16: 3105 + 207 = 3312
Step 17: 3312 + 207 = 3519
Step 18: 3519 + 207 = 3726
Step 19: 3726 + 207 = 3933
Step 20: 3933 + 207 = 4140
Step 21: 4140 + 207 = 4347
Step 22: 4347 + 207 = 4554
Step 23: 4554 + 207 = 4761
Step 24: 4761 + 207 = 4968
Step 25: 4968 + 207 = 5175
Step 26: 5175 + 207 = 5382
Step 27: 5382 + 207 = 5589
Step 28: 5589 + 207 = 5796
Step 29: 5796 + 207 = 6003
Step 30: 6003 + 207 = 6210
Step 31: 6210 + 207 = 6417
Step 32: 6417 + 207 = 6624
Step 33: 6624 + 207 = 6831
Step 34: 6831 + 207 = 7038
Step 35: 7038 + 207 = 7245
Step 36: 7245 + 207 = 7452
Step 37: 7452 + 207 = 7659
Step 38: 7659 + 207 = 7866
Step 39: 7866 + 207 = 8073
Step 40: 8073 + 207 = 8280
Step 41: 8280 + 207 = 8487
Step 42: 8487 + 207 = 8694
Step 43: 8694 + 207 = 8901
Step 44: 8901 + 207 = 9108
Step 45: 9108 + 207 = 9315
Step 46: 9315 + 207 = 9522
Step 47: 9522 + 207 = 9729
Step 48: 9729 + 207 = 9936
Step 49: 9936 + 207 = 10143
Step 50: 10143 + 207 = 10350

So, 207*50 = 10350
