OK, let's work through this together. We're starting with 974 and we're going to multiply it by 45, which means we add 974 to itself 45 times.
Step 1: 0 + 974 = 974
Step 2: 974 + 974 = 1948
Step 3: 1948 + 974 = 2922
Step 4: 2922 + 974 = 3896
Step 5: 3896 + 974 = 4870
Step 6: 4870 + 974 = 5844
Step 7: 5844 + 974 = 6818
Step 8: 6818 + 974 = 7792
Step 9: 7792 + 974 = 8766
Step 10: 8766 + 974 = 9740
Step 11: 9740 + 974 = 10714
Step 12: 10714 + 974 = 11688
Step 13: 11688 + 974 = 12662
Step 14: 12662 + 974 = 13636
Step 15: 13636 + 974 = 14610
Step 16: 14610 + 974 = 15584
Step 17: 15584 + 974 = 16558
Step 18: 16558 + 974 = 17532
Step 19: 17532 + 974 = 18506
Step 20: 18506 + 974 = 19480
Step 21: 19480 + 974 = 20454
Step 22: 20454 + 974 = 21428
Step 23: 21428 + 974 = 22402
Step 24: 22402 + 974 = 23376
Step 25: 23376 + 974 = 24350
Step 26: 24350 + 974 = 25324
Step 27: 25324 + 974 = 26298
Step 28: 26298 + 974 = 27272
Step 29: 27272 + 974 = 28246
Step 30: 28246 + 974 = 29220
Step 31: 29220 + 974 = 30194
Step 32: 30194 + 974 = 31168
Step 33: 31168 + 974 = 32142
Step 34: 32142 + 974 = 33116
Step 35: 33116 + 974 = 34090
Step 36: 34090 + 974 = 35064
Step 37: 35064 + 974 = 36038
Step 38: 36038 + 974 = 37012
Step 39: 37012 + 974 = 37986
Step 40: 37986 + 974 = 38960
Step 41: 38960 + 974 = 39934
Step 42: 39934 + 974 = 40908
Step 43: 40908 + 974 = 41882
Step 44: 41882 + 974 = 42856
Step 45: 42856 + 974 = 43830

So, 974*45 = 43830
