OK, let's crack this. We're given 279 and our task is to multiply it by 39. Essentially, we'll be adding 279 to itself 39 times.
Step 1: 0 + 279 = 279
Step 2: 279 + 279 = 558
Step 3: 558 + 279 = 837
Step 4: 837 + 279 = 1116
Step 5: 1116 + 279 = 1395
Step 6: 1395 + 279 = 1674
Step 7: 1674 + 279 = 1953
Step 8: 1953 + 279 = 2232
Step 9: 2232 + 279 = 2511
Step 10: 2511 + 279 = 2790
Step 11: 2790 + 279 = 3069
Step 12: 3069 + 279 = 3348
Step 13: 3348 + 279 = 3627
Step 14: 3627 + 279 = 3906
Step 15: 3906 + 279 = 4185
Step 16: 4185 + 279 = 4464
Step 17: 4464 + 279 = 4743
Step 18: 4743 + 279 = 5022
Step 19: 5022 + 279 = 5301
Step 20: 5301 + 279 = 5580
Step 21: 5580 + 279 = 5859
Step 22: 5859 + 279 = 6138
Step 23: 6138 + 279 = 6417
Step 24: 6417 + 279 = 6696
Step 25: 6696 + 279 = 6975
Step 26: 6975 + 279 = 7254
Step 27: 7254 + 279 = 7533
Step 28: 7533 + 279 = 7812
Step 29: 7812 + 279 = 8091
Step 30: 8091 + 279 = 8370
Step 31: 8370 + 279 = 8649
Step 32: 8649 + 279 = 8928
Step 33: 8928 + 279 = 9207
Step 34: 9207 + 279 = 9486
Step 35: 9486 + 279 = 9765
Step 36: 9765 + 279 = 10044
Step 37: 10044 + 279 = 10323
Step 38: 10323 + 279 = 10602
Step 39: 10602 + 279 = 10881

So, 279*39 = 10881
