Let's roll up our sleeves and solve this. We have 323 and we're going to multiply it by 27, essentially adding 323 to itself 27 times.
Step 1: 0 + 323 = 323
Step 2: 323 + 323 = 646
Step 3: 646 + 323 = 969
Step 4: 969 + 323 = 1292
Step 5: 1292 + 323 = 1615
Step 6: 1615 + 323 = 1938
Step 7: 1938 + 323 = 2261
Step 8: 2261 + 323 = 2584
Step 9: 2584 + 323 = 2907
Step 10: 2907 + 323 = 3230
Step 11: 3230 + 323 = 3553
Step 12: 3553 + 323 = 3876
Step 13: 3876 + 323 = 4199
Step 14: 4199 + 323 = 4522
Step 15: 4522 + 323 = 4845
Step 16: 4845 + 323 = 5168
Step 17: 5168 + 323 = 5491
Step 18: 5491 + 323 = 5814
Step 19: 5814 + 323 = 6137
Step 20: 6137 + 323 = 6460
Step 21: 6460 + 323 = 6783
Step 22: 6783 + 323 = 7106
Step 23: 7106 + 323 = 7429
Step 24: 7429 + 323 = 7752
Step 25: 7752 + 323 = 8075
Step 26: 8075 + 323 = 8398
Step 27: 8398 + 323 = 8721

So, 323*27 = 8721
