OK, let's crack this. We're given 767 and our task is to multiply it by 40. Essentially, we'll be adding 767 to itself 40 times.
Step 1: 0 + 767 = 767
Step 2: 767 + 767 = 1534
Step 3: 1534 + 767 = 2301
Step 4: 2301 + 767 = 3068
Step 5: 3068 + 767 = 3835
Step 6: 3835 + 767 = 4602
Step 7: 4602 + 767 = 5369
Step 8: 5369 + 767 = 6136
Step 9: 6136 + 767 = 6903
Step 10: 6903 + 767 = 7670
Step 11: 7670 + 767 = 8437
Step 12: 8437 + 767 = 9204
Step 13: 9204 + 767 = 9971
Step 14: 9971 + 767 = 10738
Step 15: 10738 + 767 = 11505
Step 16: 11505 + 767 = 12272
Step 17: 12272 + 767 = 13039
Step 18: 13039 + 767 = 13806
Step 19: 13806 + 767 = 14573
Step 20: 14573 + 767 = 15340
Step 21: 15340 + 767 = 16107
Step 22: 16107 + 767 = 16874
Step 23: 16874 + 767 = 17641
Step 24: 17641 + 767 = 18408
Step 25: 18408 + 767 = 19175
Step 26: 19175 + 767 = 19942
Step 27: 19942 + 767 = 20709
Step 28: 20709 + 767 = 21476
Step 29: 21476 + 767 = 22243
Step 30: 22243 + 767 = 23010
Step 31: 23010 + 767 = 23777
Step 32: 23777 + 767 = 24544
Step 33: 24544 + 767 = 25311
Step 34: 25311 + 767 = 26078
Step 35: 26078 + 767 = 26845
Step 36: 26845 + 767 = 27612
Step 37: 27612 + 767 = 28379
Step 38: 28379 + 767 = 29146
Step 39: 29146 + 767 = 29913
Step 40: 29913 + 767 = 30680

So, 767*40 = 30680
