Step 12: 8767 + 797 = 9564
Step 13: 9564 + 797 = 10361
Step 14: 10361 + 797 = 11158
Step 15: 11158 + 797 = 11955
Step 16: 11955 + 797 = 12752
Step 17: 12752 + 797 = 13549
Step 18: 13549 + 797 = 14346
Step 19: 14346 + 797 = 15143
Step 20: 15143 + 797 = 15940
Step 21: 15940 + 797 = 16737
Step 22: 16737 + 797 = 17534
Step 23: 17534 + 797 = 18331
Step 24: 18331 + 797 = 19128
Step 25: 19128 + 797 = 19925
Step 26: 19925 + 797 = 20722
Step 27: 20722 + 797 = 21519
Step 28: 21519 + 797 = 22316
Step 29: 22316 + 797 = 23113
Step 30: 23113 + 797 = 23910
Step 31: 23910 + 797 = 24707
Step 32: 24707 + 797 = 25504
Step 33: 25504 + 797 = 26301
Step 34: 26301 + 797 = 27098
Step 35: 27098 + 797 = 27895
Step 36: 27895 + 797 = 28692
Step 37: 28692 + 797 = 29489
Step 38: 29489 + 797 = 30286
Step 39: 30286 + 797 = 31083
Step 40: 31083 + 797 = 31880
Step 41: 31880 + 797 = 32677

So, 797*41 = 32677
