Let's get this math done. We have 910 and we're going to multiply it by 38. This is the same as taking 910 and adding it to itself 38 times.
Step 1: 0 + 910 = 910
Step 2: 910 + 910 = 1820
Step 3: 1820 + 910 = 2730
Step 4: 2730 + 910 = 3640
Step 5: 3640 + 910 = 4550
Step 6: 4550 + 910 = 5460
Step 7: 5460 + 910 = 6370
Step 8: 6370 + 910 = 7280
Step 9: 7280 + 910 = 8190
Step 10: 8190 + 910 = 9100
Step 11: 9100 + 910 = 10010
Step 12: 10010 + 910 = 10920
Step 13: 10920 + 910 = 11830
Step 14: 11830 + 910 = 12740
Step 15: 12740 + 910 = 13650
Step 16: 13650 + 910 = 14560
Step 17: 14560 + 910 = 15470
Step 18: 15470 + 910 = 16380
Step 19: 16380 + 910 = 17290
Step 20: 17290 + 910 = 18200
Step 21: 18200 + 910 = 19110
Step 22: 19110 + 910 = 20020
Step 23: 20020 + 910 = 20930
Step 24: 20930 + 910 = 21840
Step 25: 21840 + 910 = 22750
Step 26: 22750 + 910 = 23660
Step 27: 23660 + 910 = 24570
Step 28: 24570 + 910 = 25480
Step 29: 25480 + 910 = 26390
Step 30: 26390 + 910 = 27300
Step 31: 27300 + 910 = 28210
Step 32: 28210 + 910 = 29120
Step 33: 29120 + 910 = 30030
Step 34: 30030 + 910 = 30940
Step 35: 30940 + 910 = 31850
Step 36: 31850 + 910 = 32760
Step 37: 32760 + 910 = 33670
Step 38: 33670 + 910 = 34580

So, 910*38 = 34580
