Sure thing, let's get straight to it. We start with 278 and we're going to multiply it by 39, which means adding 278 to itself 39 times.
Step 1: 0 + 278 = 278
Step 2: 278 + 278 = 556
Step 3: 556 + 278 = 834
Step 4: 834 + 278 = 1112
Step 5: 1112 + 278 = 1390
Step 6: 1390 + 278 = 1668
Step 7: 1668 + 278 = 1946
Step 8: 1946 + 278 = 2224
Step 9: 2224 + 278 = 2502
Step 10: 2502 + 278 = 2780
Step 11: 2780 + 278 = 3058
Step 12: 3058 + 278 = 3336
Step 13: 3336 + 278 = 3614
Step 14: 3614 + 278 = 3892
Step 15: 3892 + 278 = 4170
Step 16: 4170 + 278 = 4448
Step 17: 4448 + 278 = 4726
Step 18: 4726 + 278 = 5004
Step 19: 5004 + 278 = 5282
Step 20: 5282 + 278 = 5560
Step 21: 5560 + 278 = 5838
Step 22: 5838 + 278 = 6116
Step 23: 6116 + 278 = 6394
Step 24: 6394 + 278 = 6672
Step 25: 6672 + 278 = 6950
Step 26: 6950 + 278 = 7228
Step 27: 7228 + 278 = 7506
Step 28: 7506 + 278 = 7784
Step 29: 7784 + 278 = 8062
Step 30: 8062 + 278 = 8340
Step 31: 8340 + 278 = 8618
Step 32: 8618 + 278 = 8896
Step 33: 8896 + 278 = 9174
Step 34: 9174 + 278 = 9452
Step 35: 9452 + 278 = 9730
Step 36: 9730 + 278 = 10008
Step 37: 10008 + 278 = 10286
Step 38: 10286 + 278 = 10564
Step 39: 10564 + 278 = 10842

So, 278*39 = 10842
