Let's roll up our sleeves and solve this. We have 797 and we're going to multiply it by 36, essentially adding 797 to itself 36 times.
Step 1: 0 + 797 = 797
Step 2: 797 + 797 = 1594
Step 3: 1594 + 797 = 2391
Step 4: 2391 + 797 = 3188
Step 5: 3188 + 797 = 3985
Step 6: 3985 + 797 = 4782
Step 7: 4782 + 797 = 5579
Step 8: 5579 + 797 = 6376
Step 9: 6376 + 797 = 7173
Step 10: 7173 + 797 = 7970
Step 11: 7970 + 797 = 8767
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

So, 797*36 = 28692
