OK, let's crack this. We're given 737 and our task is to multiply it by 40. Essentially, we'll be adding 737 to itself 40 times.
Step 1: 0 + 737 = 737
Step 2: 737 + 737 = 1474
Step 3: 1474 + 737 = 2211
Step 4: 2211 + 737 = 2948
Step 5: 2948 + 737 = 3685
Step 6: 3685 + 737 = 4422
Step 7: 4422 + 737 = 5159
Step 8: 5159 + 737 = 5896
Step 9: 5896 + 737 = 6633
Step 10: 6633 + 737 = 7370
Step 11: 7370 + 737 = 8107
Step 12: 8107 + 737 = 8844
Step 13: 8844 + 737 = 9581
Step 14: 9581 + 737 = 10318
Step 15: 10318 + 737 = 11055
Step 16: 11055 + 737 = 11792
Step 17: 11792 + 737 = 12529
Step 18: 12529 + 737 = 13266
Step 19: 13266 + 737 = 14003
Step 20: 14003 + 737 = 14740
Step 21: 14740 + 737 = 15477
Step 22: 15477 + 737 = 16214
Step 23: 16214 + 737 = 16951
Step 24: 16951 + 737 = 17688
Step 25: 17688 + 737 = 18425
Step 26: 18425 + 737 = 19162
Step 27: 19162 + 737 = 19899
Step 28: 19899 + 737 = 20636
Step 29: 20636 + 737 = 21373
Step 30: 21373 + 737 = 22110
Step 31: 22110 + 737 = 22847
Step 32: 22847 + 737 = 23584
Step 33: 23584 + 737 = 24321
Step 34: 24321 + 737 = 25058
Step 35: 25058 + 737 = 25795
Step 36: 25795 + 737 = 26532
Step 37: 26532 + 737 = 27269
Step 38: 27269 + 737 = 28006
Step 39: 28006 + 737 = 28743
Step 40: 28743 + 737 = 29480

So, 737*40 = 29480
