Let's get this math done. We have 43 and we're going to multiply it by 38. This is the same as taking 43 and adding it to itself 38 times.
Step 1: 0 + 43 = 43
Step 2: 43 + 43 = 86
Step 3: 86 + 43 = 129
Step 4: 129 + 43 = 172
Step 5: 172 + 43 = 215
Step 6: 215 + 43 = 258
Step 7: 258 + 43 = 301
Step 8: 301 + 43 = 344
Step 9: 344 + 43 = 387
Step 10: 387 + 43 = 430
Step 11: 430 + 43 = 473
Step 12: 473 + 43 = 516
Step 13: 516 + 43 = 559
Step 14: 559 + 43 = 602
Step 15: 602 + 43 = 645
Step 16: 645 + 43 = 688
Step 17: 688 + 43 = 731
Step 18: 731 + 43 = 774
Step 19: 774 + 43 = 817
Step 20: 817 + 43 = 860
Step 21: 860 + 43 = 903
Step 22: 903 + 43 = 946
Step 23: 946 + 43 = 989
Step 24: 989 + 43 = 1032
Step 25: 1032 + 43 = 1075
Step 26: 1075 + 43 = 1118
Step 27: 1118 + 43 = 1161
Step 28: 1161 + 43 = 1204
Step 29: 1204 + 43 = 1247
Step 30: 1247 + 43 = 1290
Step 31: 1290 + 43 = 1333
Step 32: 1333 + 43 = 1376
Step 33: 1376 + 43 = 1419
Step 34: 1419 + 43 = 1462
Step 35: 1462 + 43 = 1505
Step 36: 1505 + 43 = 1548
Step 37: 1548 + 43 = 1591
Step 38: 1591 + 43 = 1634

So, 43*38 = 1634
