Without delay, let's solve this. We've got 38 and we will be multiplying it by 50, that is, adding 38 to itself 50 times.
Step 1: 0 + 38 = 38
Step 2: 38 + 38 = 76
Step 3: 76 + 38 = 114
Step 4: 114 + 38 = 152
Step 5: 152 + 38 = 190
Step 6: 190 + 38 = 228
Step 7: 228 + 38 = 266
Step 8: 266 + 38 = 304
Step 9: 304 + 38 = 342
Step 10: 342 + 38 = 380
Step 11: 380 + 38 = 418
Step 12: 418 + 38 = 456
Step 13: 456 + 38 = 494
Step 14: 494 + 38 = 532
Step 15: 532 + 38 = 570
Step 16: 570 + 38 = 608
Step 17: 608 + 38 = 646
Step 18: 646 + 38 = 684
Step 19: 684 + 38 = 722
Step 20: 722 + 38 = 760
Step 21: 760 + 38 = 798
Step 22: 798 + 38 = 836
Step 23: 836 + 38 = 874
Step 24: 874 + 38 = 912
Step 25: 912 + 38 = 950
Step 26: 950 + 38 = 988
Step 27: 988 + 38 = 1026
Step 28: 1026 + 38 = 1064
Step 29: 1064 + 38 = 1102
Step 30: 1102 + 38 = 1140
Step 31: 1140 + 38 = 1178
Step 32: 1178 + 38 = 1216
Step 33: 1216 + 38 = 1254
Step 34: 1254 + 38 = 1292
Step 35: 1292 + 38 = 1330
Step 36: 1330 + 38 = 1368
Step 37: 1368 + 38 = 1406
Step 38: 1406 + 38 = 1444
Step 39: 1444 + 38 = 1482
Step 40: 1482 + 38 = 1520
Step 41: 1520 + 38 = 1558
Step 42: 1558 + 38 = 1596
Step 43: 1596 + 38 = 1634
Step 44: 1634 + 38 = 1672
Step 45: 1672 + 38 = 1710
Step 46: 1710 + 38 = 1748
Step 47: 1748 + 38 = 1786
Step 48: 1786 + 38 = 1824
Step 49: 1824 + 38 = 1862
Step 50: 1862 + 38 = 1900

So, 38*50 = 1900
