OK, let's crack this. We're given 937 and our task is to multiply it by 43. Essentially, we'll be adding 937 to itself 43 times.
Step 1: 0 + 937 = 937
Step 2: 937 + 937 = 1874
Step 3: 1874 + 937 = 2811
Step 4: 2811 + 937 = 3748
Step 5: 3748 + 937 = 4685
Step 6: 4685 + 937 = 5622
Step 7: 5622 + 937 = 6559
Step 8: 6559 + 937 = 7496
Step 9: 7496 + 937 = 8433
Step 10: 8433 + 937 = 9370
Step 11: 9370 + 937 = 10307
Step 12: 10307 + 937 = 11244
Step 13: 11244 + 937 = 12181
Step 14: 12181 + 937 = 13118
Step 15: 13118 + 937 = 14055
Step 16: 14055 + 937 = 14992
Step 17: 14992 + 937 = 15929
Step 18: 15929 + 937 = 16866
Step 19: 16866 + 937 = 17803
Step 20: 17803 + 937 = 18740
Step 21: 18740 + 937 = 19677
Step 22: 19677 + 937 = 20614
Step 23: 20614 + 937 = 21551
Step 24: 21551 + 937 = 22488
Step 25: 22488 + 937 = 23425
Step 26: 23425 + 937 = 24362
Step 27: 24362 + 937 = 25299
Step 28: 25299 + 937 = 26236
Step 29: 26236 + 937 = 27173
Step 30: 27173 + 937 = 28110
Step 31: 28110 + 937 = 29047
Step 32: 29047 + 937 = 29984
Step 33: 29984 + 937 = 30921
Step 34: 30921 + 937 = 31858
Step 35: 31858 + 937 = 32795
Step 36: 32795 + 937 = 33732
Step 37: 33732 + 937 = 34669
Step 38: 34669 + 937 = 35606
Step 39: 35606 + 937 = 36543
Step 40: 36543 + 937 = 37480
Step 41: 37480 + 937 = 38417
Step 42: 38417 + 937 = 39354
Step 43: 39354 + 937 = 40291

So, 937*43 = 40291
